… secondo l’analisi della Stratfor:

The U.S. military has a global presence, and sequestration would have appreciable effects on this in certain areas. Potentially, the hardest hit region will be the Pacific, which has been the focus of the United States’ new strategy. If the United States wants to continue pivoting its focus toward the Pacific, the military would have to draw more resources than originally planned.[…]

The U.S. military’s footprint is being reduced in a few other areas. The combat zone in Afghanistan has 66,000 troops, with 34,000 scheduled to come home by the end of the year. All but around 8,000 will return home by the end of 2014. The 5th Fleet headquartered in Bahrain is being affected by the Navy’s decision to have only one carrier in the Persian Gulf. Europe is seeing a reduction from four brigade combat teams to two, which was already planned and is another reinforced trend. The U.S. ground presence in Africa and South America should be relatively unchanged, since these predominantly involve special operations forces — the kind of deployment that is already being emphasized over larger conventional forces.
The single biggest capability gap that will develop will be the U.S. military’s surge capacity. If the Syria-Iraq-Lebanon corridor were to become more unstable, the United States will not be able to respond with the same force structure it had in the past. The U.S. military can still shift its assets to different regions to attain its strategic goals, but those assets will come from a smaller resource pool, and shifting them will lessen the presence in some other region. The military’s ability to use one of its softer political tools — joint military exercises — will also be at risk.

This is not to say that the U.S. military will be wrecked immediately or that its condition is anywhere near that of the Russian military in the 1990s. A military’s effectiveness is measured against its potential opponents, and the United States has enjoyed a large gap for decades. However, if a military is not growing in capabilities and other militaries or groups are, then its relative power is decreasing. This means that after sequestration is implemented or the continuing resolution is maintained, the U.S. military will remain dominant for years to come, but not as dominant as it has been relative to other forces.
