we could be quite certain the Israelis and Brits would get beat up with us
You are joking right? You do realise that in 2001, 75% of the British public did not want to be part of the Afghan war. http://www.globalpolicy.org/component/content/article/154/26553.htm1
From your linked article:
The biggest poll of world opinion was carried out by Gallup International in 37 countries in late September (Gallup International 2001). It found that apart from the US, Israel and India a majority of people in every country surveyed preferred extradition and trial of suspects to a US attack.
This was what we wanted as well. Then the Taliban told us to go fuck ourselves. Then we blew the shit out of them. Every country in the world either got behind us or was at least smart enough to get out of the way of the injured, rabid, bulldog that Afghanistan had just poked with a stick.
I'm with you in that Iraq was unjustified and stupid and nobody had any business in that mess (least of all the U.S.), and you can argue that Afghanistan has been poorly managed, but that initial invasion was inevitable and pretty thoroughly justified.
To connect up with a more current possibility - if North Korea were to do something as thoroughly boneheaded as the launch and detonate a nuclear weapon at the western seaboard of the United States I am absolutely certain that Britain, Israel, and probably the majority of the free world would jump on board with an invasion. Heck, if NK was that utterly stupid, China would probably bitch slap them for it.
