The USA also had other great achievements in the last 100 years:
- helped turn the tide against the German military machine in WW1;
- helped turn the tide against the maniacal German Facist regime in WW11,a regime that tortured and murdered millions of innocent people;
- saved millions of South Koreans from the North Korean maniac, a maniac that has tortured and starved to death millions of his own people;
- saved Berlin and its inhabitants, from the scourge of despotic Soviet Communism, a regime that had no hesitation in torturing and starving to death millions of its own people;
- defeated the despotic Japanese military machine, a machine that tortured and killed millions in the name of Imperial Japan;
- by the utilisation of its superior airpower was instrumental in bringing the post WW11 Yugoslav conflict to a conclusion;
- introduced the real meaning of Democracy to the world, although unfortunately, for quite some time, it did not cover its non-white inhabitants;
- landed the first human beings on the Moon;
- is one of the best and successful countries on earth for medical and scientific research;
- was the only real bulwark against the advance of totalitarian and tyrannical Communism.
The world would be a much worse place without it.
One can measure the level of its success by the extravagant language of those who continually criticise it.
