Russia, Iran, Turkey, Jordan, Israel, UK, and would you believe it, even the USA are fighting in Syria. Many more nations are supplying money and arms .

600K dead, at least, almost 10x the casualties of Israel v. Palestine (80K) and heavy international military involvement, for 15 years or so.

Russia v. Ukraine is now over 2 million casualties.

US has a finger in every pie, so It's not all bad news, gentle reader! Boeing's revenue is up 2 billion, that's nice.
