Not only is the US sending 31 Abrams tanks to Ukraine, but he is also sending Bradley Fighting Vehicles and Stryker Armored personnel carriers. Plus Germany and other NATO Allies are sending even more. Remember Russia invaded eastern Ukraine long before Biden was President.
Oh, and let’s not forget Trump was impeached for attempting to extort Ukraine - trying to trade weapons for help with his re-election campaign, in the “perfect phone call”. He ultimately lost his election, lied and said it was stolen, then encouraged a mob of idiots to raid the Capitol, thus ending our record of a peaceful transfer of power for the first time in American history. What a disgrace!
