"You can negotiate with Putin without giving him a one-on-one summit with POTUS on American soil."

I've only read a few snippets of this thread, so apologies if this has already been covered:
Why would Ukraine trust any agreement made between Trump and Putin ?
Putin has totally disdained Peace Pacts before. Ukraine is well aware of that.
Trump breaks trade agreements like it's nothing. Trump breeches contracts like
they didn't exist.
Didn't the US and Russia agree that if Ukraine gave up their nukes, then the US and
Russia would guarantee Ukraine's safety ?? What the hell happened to that ??

So now Ukraine, and Europe, are going to abide by any agreement reached between Trump
and Putin, despite their proven history of breaking contracts.
Sounds pretty farfetched to me.

"Ukraine gave up its nuclear weapons after the collapse of the Soviet Union. In 1994, Ukraine agreed to transfer all remaining nuclear warheads to Russia in exchange for security assurances from the United States, the United Kingdom, and Russia, formalized in the Budapest Memorandum. "
