> Bush assembled a serious international coalition before going for Iraq
Uh? Bush failed to assemble a coalition by providing dubious and faked proofs of supposed WMDs and chemical weapons. The Europeans and especially the French didn't fall for it. The only one who did was Tony Blair and he's still paying the price both domestically in the UK and abroad. AFAIK, Trump isn't planning to send troops in Venezuela on the scale Bush did in Iraq.
To quote from internet history, the famous "you forgot Poland" from the 2004 presidential debates:
"KERRY: ...when we went in, there were three countries: Great Britain, Australia and the United States. That's not a grand coalition. We can do better.
LEHRER: Thirty seconds, Mr. President
BUSH: Well, actually, he forgot Poland. And now there's 30 nations involved, standing side by side with our American troops."
> The only one who [fell for it] was Tony Blair
I wish that were true, but as somebody from Denmark I can tell you that it isn't
> The only one who did was Tony Blair
"You forgot Poland."
Many European nations contributed, it wasn't just the UK. The french were basically the only NATO members who didn't contribute
Tony Blair wasn't fooled by the fake WMD evidence - he was fully on board and deliberately went against the advice and evidence of the intelligence services.
He should be tried for war crimes for dragging the UK into a war on false pretences.
Germany did send troops. Correct me if I'm wrong.
(edit: I was wrong. Italy, UK, Spain, Poland, Turkey among others.) Anyway, the point is that there was some sort of coalition.
Bush successfully assembled a coalition to invade Afghanistan. He didn't even promise that there'd be WMDs there, he just said "They gots terrorists" and a large portion of the UN joined in the invasion.
Upon reflection, the justifications to invade Afghanistan were every bit as flimsy as the justification to invade Iraq.
The Spanish president at the time, Aznar, also "fell for it" (probably didn't believe it but played along just for posturing, because he loved being pictured with Bush) and paid the price domestically. The best thing is that he was such a toady, ignoring the Spanish people's will becuase he wanted to be seen with the big boys and to be their equal, and you don't even remember him when you recall that coalition. The fact that you haven't remembered him has actually made me smile hard.
