How to respond to Russia's actions in Ukraine? #tellusatoday

We asked our followers on Twitter how the U.S. should respond to Russia's actions in Ukraine. Comments are edited for clarity and grammar:

Impose immediate sanctions against Russian government and businesses, then ask Ukraine to join NATO. Russia can't afford economic isolation.

— @pfaliano

Start with quick and definite economic sanctions and put military support for Ukraine on the table.

— @SedoniaF

We have a security deal with Ukraine, signed when it gave up nukes. Our credibility is on the line. The world is looking.

Vladimir Putin has shown that he believes President Obama won't act. And Putin has to show he will act now.

— @BiggzIrvin

The U.S. should work with the U.N. to suspend Russia from the U.N. Security Council. An invader has no place there.

— @BaileyPittipat

The U.S. must not back down from Putin. If we do, Ukraine will be lost.

— @firefly241

How should the U.S. respond to Russia's actions? Ukraine is in Russia's backyard; U.S. should stay away from it.
