Time for NATO to walk the talk and send troops to secure Kyiv to make sure that the Ukrainian government does not fall.
Tell me, how has all the money spent in Ukraine thus far made me more free, safer, or wealthier?
In fact, without make belief boogieman arguments that are unrealistic (The Soviet Union and Warsaw Pact are gone), what national security argument is there for our involvement?
What are you defending? Peace (a war we antagonized - NATO East expansion), democracy (Ukraine isn't one), a nations sovereignty (Ukraine is a satellite of the US), human rights (Ukraine has a horrible human rights record)?
What defensive treaty do we have with Ukraine, what do we owe them?
