We are being invaded with the assistance of our own government.
What is happening in Ukraine is not as critical to US citizens like the invasion of the US is.
You are evading the question!
AGAIN: So if we stop all shipments to Ukraine, that will somehow alter the situation on our southern border - is that what you are implying?
To imply that we can solve only one problem, or the other, but not both simultaneously would be to commit the "False Dilemma" Fallacy.
