Nope. They ask for weapons and military assistance. They ask for the means to defend themselves. I have seen no claims of guaranteed victory, just a fighting chance. It would be foolish to ever make such claims, and your making it sound as if they made such claims is disingenuous at best. We would all be better off if we stuck to facts presented or asked good questions about facts not presented, rather than making bogus claims. That applies to both sides.
Believe what you want, Ukraine had an air force made up of Russian MIGs, they begged for F-16s and to any objective person, the new jets would put them on an even level with Russia according to all the so-called experts.
My prediction still holds, more F-16s will crash for unexplained reasons, Russia has some modern air defenses, maybe not the world’s best, but capable. and Ukraine has inexperienced F-16 pilots because the plane has never been flown by Ukraine before, it’s like leading lambs to slaughter.
The dirty little secret is the countries giving up the F-16s, will probably acquire F-35s as replacements which benefits the MIC.
