No, failure to support Ukraine is not un-American.
I’ve been “debating” with these folks for months and MANY of them make statements that are right out of the left’s handbook, and certainly are anti American. And more recently, directly anti-Trump.
A few simple examples - that our own government is more of an enemy than Putin; that Putin is a Christian anti gay warrior; that our history is just as evil as the invasion of Ukraine, therefore Putin is as justified or more so than America; that support for Ukraine is racist because we don’t care about Africa.
Then there is the virulent Ukraine hatred - Ukraine is a Soros operation getting what it deserves from Putin; anyone opposing the invasion is a paid Soros operative; Zelensky is a “homo”.
Meanwhile, I’ve listed our many strategic interests in Ukraine a dozen times and when you do that they change the subject.
They are extremely misguided and need to be called out for it.
You forgot to mention the strongest argument against involvement in the Ukraine.
Defense of our own borders against foreign invaders must be the number one priority.
Failure to do so means the US is a failed state and has no business intervening anywhere in the world.
