The Biden administration has asked Congress for more than $105 billion for Ukraine, Israel and U.S. border security, but so far Republicans in the House have said no.
What does Ukraine "winning" mean to you at this point in the war? When you're targeted by a much larger nation state that has every tactical advantage against you, you're going to lose.
Look at every nation the United States has invaded over the last 60 years. Would you say any of them won? When hundreds of thousands of your people die violent deaths, it's hard to declare victory. Even if you remain independent, you lose.
