Let's not forget that while USS Steven W. Groves is tasked with stopping a very small % of the Peruvian marching powder that makes it into the US, the Iranians are building up their forces in the Persian Gulf, the Chinese are building a blue-water navy, and tinpot dictators like Chavez and Kim threaten their neighbors and world peace in general.

You are aware that ONE singular carrier group would take care of any two navies that does not include Britain right????
