USA and War

United States has been at war constantly for the last 60 years, this has made USA the most experienced nation at war games and tactics. This also allows them to experiment and improvise by first hand learning and experience. Also they can improvise not only on tactics but also on equipment and weapons delivery systems. This makes a deadly combination. There are various war scenarios, like Vietnam (Jungle warfare), Middle East (Desert warfare), both requiring different skills and equipment.
Today only USA is capable of waging a war on a truly global scale, rest all are only paper tigers.
Others if they have the equipment, the question is do they have the capability and the skills to effectively bring about the required outcome? The answer is NO.
The sooner the world realises the better, fortunately for the world USA is a democratic nation, whose people have sence of justice and fairplay.
