Marco Rubio, writing for Politico:
Russia’s illegal military incursion in the Crimea region in Ukraine is a grave violation of a nation’s sovereignty and cannot go unpunished.
First, President Obama should speak unequivocally and call this what it is: a military invasion. The Obama administration must publicly acknowledge that its “reset” with Russia is dead. The president must now accept that the only way to deal with tyrants like Vladimir Putin is with a clear understanding that they can’t be trusted and that only decisive action will deter their provocative moves.
Second, President Obama should dispatch Secretary of State John Kerry and Defense Secretary Chuck Hagel to Kiev to show U.S. support for Ukraine’s transitional government, and urge our allies in the European Union and NATO to send representatives there as well. The United States should convene an emergency meeting of NATO to develop a strong united response from the trans-Atlantic alliance. And we should send high-level delegations to our allies in Central and Eastern Europe to reinforce the fact that we are standing by them. As part of this work with our allies, we should develop a series of economic and security assurance measures to help the transitional government in Kiev remain stable and carry out a democratic transition.
Third, the United States should rally our allies to boycott this June’s G-8 summit in Sochi, Russia. And if Russian troops do not leave Ukraine immediately, Russia should be expelled from this group altogether.
Whole thing here.
