Well stand by and watch other people die then, as long as it's not you blokes, that's right isn't it?
If Trump was taken out of the equation, Putin would still have field artillery nukes and willing to use them. Then what? Do you believe he won't use them? Just let opposing nations go in with troops to fight the Russians, and see what happens. Alternatively, and again, without Trump, NATO & Co and the US (under someone else), would continue to supply arms to Ukraine, at great long term cost, boosting Zelensky's determination to oust the Russian forces, and destroying more of Ukraine and his people. He'll have to resign, or he may just get sacked by his govt.
Trump is virtually out of the negotiations now, and US aid to Ukraine has stopped, so let's see what the rest of the World can do, make or break Ukraine, the latter seems likely.
