1940, Americans sent tens of thousands of firearms and millions of rounds of ammunition to the UK. I'm sure we'd do the same for UKR, if there were time to do so.
That's why there's the second amendment that's why we need AR-15s. Ukraine has militia but it's nothing compared to ours we could raise a militia of tens of millions. Possibly even a hundred million.
They are for Americans...as long as the Constitution and Bill of Rights survive. But in one sense you are correct... cowardice and incompetence as Biden demonstrates can destroy our Constitution and make us slaves. Freedom must be PROTECTED.
