Bro I study history and have studied every civiliazation known to man, over a thousand battles and have written on over 500 generals, so let me give you a quick history lesson sense you are clearly lacking in this field.
2000 BC Summerian strong hold in the fertile cresent, oppisition from Accadians,Mesopatamian, and Babylonians
1500, Rise of the Elamites, Canaanites, and egyptians and Hebrew tribes known today as the Jews and the Arabs, yes the Arabs are Hebrew.
1000 BC, Rise of Israeli rule by Solomon, lasted 500 years till the Babylonian exile
Assyrian power by Sennecherib and his Successor
followed by Babylonian rule, king Nebudchadnezzar, 550bc
followed by Persian rule, Cyrus the great.460 bc
followed by Greek rule Alexander the great 330bc
followed by Roman rule, Julius Caeser 50bc
then Germanic tribe, Heathens, and Anglo Saxons, Between 400 and 600 ad
Arab invasions, In the Days of Mohammed, 8th century
10th century Ad capture of Jurusalem over Islam
turn of the century turned over by Saladin to Syrian rule
Post 12th century, Ottomen Empire
18 Century, French rule, Napolean
21 Century America
NOW LET`S COMPARE
Israel rule---Conquest of 40 nations and 200+ wars
Assyrian Rule ----Conquest of 32 nations 150 wars
Babylonian Rule---Conquest of 25 nations and 100 wars
Greek rule ----Conquest of 35 nations and 150 wars
Roman Rule---Conquest of 50 nations and 250 wars
America--- Conquest of 6 nations and 12- 15 wars
These are the facts my friend from the beginning of time every reigning super power has abused it`s power but America has done it the least, they hold back because modern day America is not barbaric like you claim.
