I suspect that the USA will experience great difficulty in assembling any kind of UN or NATO force for this purpose.
Partly that's a matter of public opinion. I can only speak for Australia, but opinion here, as far are I can judge, is wholly on the side of the people of the Lebanon. I haven't heard anyone in the last couple of weeks say a word in support of Israel; the people I meet express overwhelming sympathy for the people of the Lebanon, and a 'new' emotion - a developing disbelief, amounting almost to horror, at the sheer scale of the damage being done by the Israeli bombing campaign. As it happens I've seen destruction on that scale in the past; but then I'm pretty old
. Younger people have never seen anything like it before.
Another factor, less well-known to the general public, is that of military capacity. Given that any threat to Australia would have to be seaborne, resources are rightly concentrated on naval and air force 'assets'; our standing army is small (only about two brigades of infantry, plus supporting arms). We already have troops committed to several peace-keeping tasks in our own region, plus troops in Iraq and Afghanistan; and I suspect that we also have special forces committed in other places, probably including Iran.
Finally, you can sense a kind of political weariness here, a feeling that a pattern is emerging. Bush, Condi, and their associates seem increasingly to be working their way through a list of countries, causing all sorts of trouble, biting off more than they can chew, and then appealing for help from 'willing hands' - always including the Commonwealth, mainly Britain, Australia, and Canada - to help clear up the mess that the USA itself has created.
I could be wrong. But ten bucks (Australian) says that Australia, anyway, won't be sending any of our already over-stretched servicemen to the Lebanon in a hurry.
Though perhaps if Bush and Condi suggested that we contributed to a peace-keeping force to bring ISRAEL into line, they'd get a better response from this hemisphere, in terms of public opinion anyway.
