Fox News reports.

Excerpt:

Russian troops moved into Crimea Friday, U.S. officials told Fox News, prompting Ukraine to accuse Russia of an “armed invasion.”

At the White House, President Obama said the U.S. government is “deeply concerned” by reports of Russian “military movements” and warned any violation of Ukraine’s sovereignty would be “deeply destabilizing.”

“There will be costs” for any military intervention, he said, without specifying what those costs might be.

U.S. officials told Fox News they see “evidence of air and maritime movement into and out of Crimea by Russian forces” although the Pentagon declined to officially “characterize” the movement.

Agence France Press quoted a top Ukranian official as saying Russian aircraft carrying nearly 2,000 suspected troops have landed at a military air base near the regional capital of the restive Crimean peninsula.

“Thirteen Russian aircraft landed at the airport of Gvardeyskoye (near Simferopol) with 150 people in each one,” Sergiy Kunitsyn, the Ukrainian president’s special representative in Crimea, told the local ATR television channel, according to AFP. He accused Russia of an “armed invasion.”

The new developments prompted Ukraine to accuse Russia of a “military invasion and occupation” — a claim that brought an alarming new dimension to the crisis.

[Republican] Mike Rogers, chairman of the House Select Committee on Intelligence, issued a statement late Friday saying, “It appears that the Russian military now controls the Crimean peninsula.  This aggression is a threat not only to Ukraine, but to regional peace and stability.  Russia’s latest action is yet another indicator that Vladimir Putin’s hegemonic ambitions threaten U.S. interests and allies around the world.”

Why would Russia be so bold about landing troops in the Ukraine? Well, what have they learned about Obama?

Obama mocked the idea that Russia was our enemy

Remember when Obama said this about Romney?

“The 1980s are calling to ask for their foreign policy back” Obama told Romney, in one debate. And this lack of seriousness about Russia caused Obama to bungle the European missile defense deal with Russia, such that Obama basically gave away the store.

The radically leftist UK Guardian explains in this September 2009 article:

Barack Obama has abandoned the controversial Pentagon plan to build a missile defence system inEurope that had long soured relations with Russia.

In one of the sharpest breaks yet with the policies of the Bush administration, Obama said the new approach would offer “stronger, swifter and smarter” defence for the US and its allies. He said it would focus on the threat posed by Iran’s short- and medium-range missiles, rather than its intercontinental nuclear capabilities.

Obama announced the reversal officially at a news conference today. “This new approach will provide capabilities sooner, build on proven systems to offer greater defences to the threat of attack than the 2007 European missile defence programme,” he said.

He phoned the leaders of Poland and the Czech Republic last night to tell them he had dropped plans to site missile interceptors and a radar station in their respective countries. Russia had furiously opposed the project, claiming it targeted Moscow’s nuclear arsenal.

Here is the former director of the CIA James Woolsey, who served in the Clinton administration:

President Barack Obama’s administration recently threatened to veto the defense budget, citing “serious concerns” over provisions that limit the U.S. missile defense know-how that the White House is permitted to share with Moscow. This is the sort of information that Russian Prime Minister Vladimir Putin, in his earlier days, would have assigned his spies to steal. Through its single-minded pursuit of “resetting” relations with Russia, the Obama administration may simply be willing to hand over this information and, in doing so, weaken U.S. national security.

Only two days after issuing the veto threat — and as Obama tried to warm Russian President Dmitry Medvedev to U.S. missile defense plans at the G-8 Summit in Deauville, France — the House of Representatives passed the defense bill. It included the provision that the president’s team finds so offensive: Section 1228 requires that no funds can be used to provide the Russian Federation with sensitive U.S. missile defense technology.

[…]They’re right to be concerned. Tehran is thumbing its nose at Washington and doubling down on its missile program. The director of national intelligence, James Clapper, told a congressional panel in March that Iran “would likely choose missile delivery as its preferred method of delivering a nuclear weapon” and that the Islamic Republic “continues to expand the scale, reach and sophistication of its ballistic missile forces, many of which are inherently capable of carrying a nuclear payload.”

Russian assistance has contributed to the progress made by Iran’s nuclear and missile programs. Should the United States share critical information about its missile defenses with the Russians, a Russian entity — official or otherwise — could pass that information along to Tehran, enabling the Iranians to capitalize on the weaknesses in the U.S. system.

Nevertheless, the Obama administration continues to demonstrate its penchant for bargaining away missile defense, and the United States is not currently developing and deploying missile defense technology at the rate and quantity the threat demands.

Here is the leftist Washington Post in March 2013:

The Pentagon is canceling the planned fourth phase of an anti-missile system that had been scheduled for deployment in Poland in 2022. The SM3 IIb missile was significant for two reasons: It was the only interceptor planned for the Europe-based system that could have defended the United States against an attack from Iran; and it was the component of the system most decried by Russia, which claimed that it could be used against its intercontinental missiles.

As it did when it canceled a previous European missile plan in 2009, the administration insisted that its decision had nothing to do with Russia or its objections. The phase-four missile was dropped, officials said, because Congress had cut some of its funding, meaning it could not have been completed in the next decade, even while the timeline of possible ICBM threats is shortening. Officials say the money can be better spent on deploying more interceptors in the United States and improving their components. As proof that Moscow has not been appeased, the White House pointed to statements by Russian officials saying they are still unsatisfied with U.S. missile defense plans and continue to demand binding legal assurances that the system can’t be aimed at Russia.

What do you think that Putin learned from Obama’s continuous appeasement and withdrawal from Europe? Well, he learned the same lesson that Hitler learned by watching the naive pacifists who opposed him – he learned that you can bully great nations if they are lead by weaklings. And that is what caused World War II – the refusal of peaceful nations to check the aggression of a tyrant early. 

What has Obama been telling Russia?

Here he is with Medvedyev:

The best way to avoid war is to make aggressors understand that there is a cost for aggression. Obama’s many foreign policy blunders – failing to help the Iranian pro-democracy forces, failing to speak out for Georgia, failing to be tough with Russia, failing to help the right people in Syria – have made it clear to Putin that aggression will go unpunished. When Democrats re-elected this man in 2012, we basically abandoned freedom-loving countries like Ukraine to the Russian tyrant. But did Democrat voters care? Of course not. They were thinking of the 1 trillion dollars of government checks that would be handed out to them in exchange for re-electing Obama. Foreign policy and the peace of the free world was the last thing on their minds.
