No idea how many wars they've started. Their current preferred way of operating seem to be covert terrorism and not under a national flag. Look it up on Wikipedia.
At school when learning about early civilisations Mesopotamia was covered. This is the land between the two rivers, Tigris and Euphrates (meso - middle, potamus like in hippo - river) is broadly modern day Iraq.
Bit by bit my schoolboy admiration for this area started to decline. I certainly found the attitudes of the Iraqi and Kurd students at University quite uncomfortable, though the Persians were somewhat better behaved.
I recently watched (again) Lawrence of Arabia and the mess this region and its neighbours became after the collapse of the Ottoman Empire at the end of WW1.
And I've recently refreshed my memory of the Iran - Iraq war - some nice bedtime stories there:
https://en.wikipedia.org/wiki/Iran%E2%80%93Iraq_War. Chermical warfare, child soldiers, half a million dead. I seem to remember someone saying that more Muslims had been killed by Muslims than by all others put together.
I have no idea what this latest ploy is all about. And it is fairly certain that the 737 was shot down. But from what had a promising start some 5000 and more years ago what a mess that region is, and seems regularly to have been.
And Americans haven't grown out of being cowboys, but it seems like a playground for Russia, China, France, Britain and America to check out their latest weaponry and defences.
