The Iranians are obsessed with our carriers and one day they will lose restraint, especially during Hillary's presidency.
If so that's dumb on America's part. We don't need carriers to hit the Iranians - US could easily stage land-based aircraft out of Turkey, Qatar, UAE, Bahrain, Oman, Kuwait and Italy. Presumably the Iraqis and Afghans would object to using their territory for operations, although who knows. If the US needed more bases to operate from, I'm sure the Saudis would be accommodating provided the target is Iran.
