London was pretty much leveled by german air raids. Not all the way but close. But I agree with Maxxy, we should probably focus on getting there
Hardly. Buildings were destroyed, but not leveled. That implies that there's no trace of the building. Many buildings in London were left in pieces, but technically still standing. Far from leveled.
And cart, I'm with you, but didn't the US pretty much bombard Baghdad with missiles and bombers? 1991 gulf war. Sure, not on the scale that Jason in suggesting, but still. And I think you mean the UN, not NATO... Yeah, the rules weren't exactly followed during the Gulf War and the invasion of Iraq... White Phosphrus, which was declared inhumane by the Geneva Convention, because it is technically a chemical attack, was used by American troops to flush out insurgents in Iraq. In war, rules tend to be broken. A lot.

If this is taking place in america, then there would be more reason NOT to use arty and strikes. It would destroy much of the city and cause millions of damage. Not to mention irreplaceable damage to monuments and the sort. Tanks are already pushing it, but if I'm controlling the other side, there won't be an airstrike or artillery unless it was an extreme situation. Even capture of a city would not warrant that as well. Maybe if the leaders of the side hunting down the supers were in danger, or imminent destruction of a war factory would warrant a strike. And it would not be made lightly.
If there a civilians around, air support and artillery would likely be declared not an opinion anyway, killing civies is a great way to get the public on the other side..
