Cruz wants to arm them too. My opinion is that although it is a sad thing the Ukraine is a (nuclear armed to the teeth) Russian interest led by an unstable leader. I wouldn’t arm the Ukraine against the Russians.
The way this works is that we will give weapons to a government that most of its own people are unwilling to support. Said weapons will then be sold or traded by the kleptocrats at a steep discount to the very people they are supposedly fighting.
Arm them NOW!
