*Devils advocate* Mabye if Putin was included and was taken seriously, this sort of thing wouldnt have happened. (I dont actually 100% believe this)
The mistake you're making is looking at it as black/white, 0/1, wet/dry, etc. The world isn't that simple, yes Trump was Putin's lap dog when it came to trade/economic matters, but on matters of defence/military he was harder on Russia than any president since Reagan, Putin was outright afraid to mess with him especially after Trump humiliated him in Syria. If you don't know what I'm referring too there, Putin was trying to strongman in Syria and act all big for Assad, Trump basically called him and said "I'm about to blow up that Syrian base your boys are at, tell them they got x mins to leave and not to warn the Syrians or I won't call you next time". Putin not only got made to look like a weak idiot but got made to look like a weak idiot in front of Assad, the very dictator he was trying to impress because he had to let all of Assad's dudes get missiles up the *** to avoid upsetting Trump.
It's 50k+ ft in altitude, will take a pricey rocket to blow one up, for what benefit when it'll just get replaced
Being soft on them? he charged china billions of dollars to export its steel into america which it had never had to do before
Please explain to me how Trump had China "on side", when it was Trump that started the trade war with China and the whole anti China rhetoric? What have you been doing for the last 5 years to come away with that absurd point of view? I was in Hanoi, Vietnam at the same time as Trump and Kim Jong Un when they met (Trump's cavalcade drove right past me) and remember thinking at the time "well done Trump", but what came of that? Absolutely sod all.
