Your response proves you know nothing about negotiation. Your style of Republican gives everything and gets nothing. It’s what’s led many to the realization that perhaps the leaders in the GOP WANT to get nothing - because they and the Democrats are on the same side.
The reality - as much as you may not like it - is that you don't have 40 Republicans willing to kill aid to Ukraine over wall funding, and there is absolutely no way the Dems would agree to wall funding. So what we get is some drawn-out statement of principle from Republicans saying they never agree, and then Democrats with enough Republican support would end up ramming through what they what they want anyway.
The truth is that funding for Ukraine has broader support than does the Wall - majority in both parties. That's why holding it hostage is a doomed effort.
