You're kidding, right? What a totally ridiculous question. You actually doubt that the U.S. is the "the greatest fighting force on the planet called Earth..."? The answer to your question as to what makes the U.S. Number One militarily, is that it has poured billions and billions of dollars into perfecting the art and science of war. Much more than any other country on Earth!

Does any other country on Earth have:

Aircraft carriers, strategic stratospheric bombers, nuclear submarines, intercontinental ballistic missiles (on land, sea and air -- and maybe in space too), stealth aircraft, spy satellites, microwave beam weapons (the death ray), the Airborne Laser to shoot down missiles, unmanned aerial vehicles like the Predator and Global Hawk, tank busters like the A-10 Warthog and Apache Longbow helicopter gunship, the M.O.A.B. (Mother Of All Bombs), plus watch FutureWeapons on The Discovery Channel for all the whiz-bang weapons that the U.S is developing still! It's enough to straighten your curly hair, to see what's on the drawing boards and in the field being developed to better kill one's fellow man. You actually have to ask what makes the U.S. the most powerful military force that there's ever been on the planet Earth?

The problem with the U.S. is that yes, it has all the big, bad weapons, but it lacks the intestinal fortitude to use them to their full capability. In other words, it's too soft to really be a true bad-ass. Its leaders have too much compassion or cowardice to really go all out and wipe out its enemies off the face of the Earth and simply take what it wants. I find this rather puzzling that it has this huge arsenal, yet it doesn't use it to get the natural resources it needs, like petroleum from the Middle East. It just makes those camel jockeys in Saudi Arabia call the shots while Americans keep paying more and more for gasoline, food and everything else, as oil keeps going up and up.

It could have easily carpet-bombed Iraq into rubble from 50,000 feet with B-52s or launch wave after wave of cruise missiles from offshore and not have risked even one American soldier. Did it do that? No. Why? It does not have the stomach to kill civilians. Oh, boo hoo hoo. Please. The big, bad Uncle Sam is a paper tiger that is afraid to eat all the villagers when it comes down to it. What a pathetic and incompetent country it is! The Roman Empire, for example, had no qualms to do what was needed to be done, in order to remain the number one superpower of its day. So, too did other empires. The Spartans, the Huns, the Chinese, the British, the Nazis, the Japanese, the Soviets, -- but NOT the Americans. This softness and lack of will to fully exercise power, is the U.S.'s Achilles' Heel and will lead to its destruction.
