@claudiu I often wondered that kind of thing when i was a kid. I used to think that the leaders should be made to have a boxing match. I was 12 and it was 1988. Regan and Gorbachev in the ring!
Historically, the world has come through arguably worse situations, such as the fall of the soviet union itself, when the nukes were literally laying around unguarded. .
The most obvious short term solution is for the Ukrainian leadership to sign the peace deal as it is. That would stop the war.
Whether it’s a good medium or long-term solution, i am not so sure. It really depends on what Putin is really trying to achieve.
Is it an energy war over the oil and gas in Ukraine? In which case, it seems that signing the deal would work.
But, the thing about that is rhe rhetoric that Putin used. He would then have to “de-nazify” Ukraine. Which sounds extremely ominous.
He would also have to then decide what to do about the leadership, considering the other claims that the are “drug addicts” (and nazis).
He could reel that statement back in to be speaking specifically about the donbas region.
However, as they are basically rather nebulous charges (the only “evidence” i saw so far of either, was from a Russian website, and Wikipedia. With some videos of racism at rhe borders. I can’t say either inspire confidence).
For Putin to actually navigate the post peace deal, there would have to be some very fast diplomacy and concessions to the existing leadership. Otherwise this will just keep rolling on. From my impression, Putin would want to restore his popularity very quickly. Those statements a so speculative though. It seemed bizarre he ordered the invasion at all, so i wonder if popularity is a consideration for him.
