Why will the Baltics be different? Do you think that the dead hand of the past (in the form of the NATO treaty) will compel Obama to act to protect nations that most Americans have never heard of? If yes keep this in mind

By 1996, Ukraine voluntarily gave up all of its nuclear arms and acceded to the Nuclear Non-Proliferation Treaty. In exchange for making the world a safer place, it received security assurances from Britain, the United States and Russia in the form of the Budapest Memorandum, signed by Bill Clinton, Boris Yeltsin, and John Major, with pledges to “respect the independence and sovereignty and the existing borders of Ukraine” and the “refrain from the threat or use of force against the territorial integrity or political independence of Ukraine.”

Do Baltic members spend lots of time and money building their political support among American politicians like Israel and Taiwan do? If not why will these politicians care if Russia retakes the Baltics?
