What If NATO Fought Every Ancient Army in History?

NATO is the most powerful military alliance in human history : 32 countries, 3.5 million soldiers, 5,000 combat aircraft. A lot of people in the comments asked for a video about NATO, so here it is. But going against any single ancient army would just be a slaughter, so this time every army in recorded history teleports to one battlefield and fights NATO at the same time. Romans, Mongols, Persians, Vikings, Spartans, Napoleon's Grande Armée, the Spanish Armada, all of them. As usual, this is your 2 am "what if" scenario, so don't take it too seriously. #history #animatedhistory #militaryhistory
