I oppose boots on the ground.
I very much oppose nation building.
Although there are some issues with international law, my basic view is that if a nation like Iran sponsors terrorism, then we should respond with terrorism also. As an example: Iranian terrorists blow up an oil refinery, the US Air Force responds by dropping 1000 tons of bombs on the most populous Iranian city. You like terrorism? Have some terrorism.
I just don't want an 18-year War with US troops occupying foreign countries with little to show for it.
Maybe buffs in the air would work.
