What happens to our troops in Ukraine if Russia invades?

Joe Biden, you may recall, spent a lot of his time as vice president meddling in the internal affairs of Ukraine. And you may wonder, why Ukraine as opposed to say, Denmark or Senegal or any of the world's other 195 countries. Simple. Because the Ukrainians were paying Joe Biden's family a million dollars a year in exchange for the work that he did. And as president, you may have noticed, Biden has continued to represent Ukrainian interests. Most recently in their dispute with Russia. 

Biden talks constantly about all the scary things he'll do if embattled Vladimir Putin dares to offend the territorial sovereignty of Biden's close friends, the Ukrainians. But one thing Joe Biden will not do, he has assured us repeatedly, is send American troops to Ukraine. Polls show Americans do not want that at all and Biden claims he's heard the message.
