Five areas of serious confrontation are in progress in the Middle East: Syrian, Iraqi, Saudi-Yemeni, Israeli-Palestinian, and Israeli-Lebanese, and all five are interconnected. The key confrontation of the five is the Syrian conflict. A victory in Syria by either side will decide the fate of the Middle East and the world. There can be no compromise, hence there is a danger of wider conflict.
If the American side wins, Syria, Iraq, and Lebanon would be partitioned along ethnic and religious lines. The biggest winner would be Israel, and the biggest losers would be the Palestinians; they would probably be expelled from their homeland. Gas and oil pipelines would be built from Qatar and other Gulf States to Europe. Also, oil and gas from Syria, Iraq, Saudi Arabia, and Yemen would be shipped to Europe via the same pipelines to lessen the European dependence on Russian gas. The dollar would be the official currency of trade. Turkey would also be a winner, but its reward would be minimal. The biggest losers of all would be the Arabs of the Middle East, they would be totally emasculated; other big losers would include the Russians and the Iranians.
If, on the other hand, the Syrian government wins, Syria would become a very powerful state and a great rebuilding would take place. The Syrian people will have enough strength to rebuild their country. With a Syrian victory, ISIS in Iraq would have no chance. Iraq would also rise up and become a powerful state. The Saudi, the Jordanian, and Gulf regimes would collapse. The Palestinians might even achieve their independence from Israel. The big winners would also be the Iranians and the Russians. The Europeans would start drifting towards Russia, one country at a time. And the biggest loser would be the British-American-Israeli Alliance. President Assad would become the national Arab hero who stood up to the British-America-Israeli Alliance and ISIS.
How the wind will blow and how history will flow remains a big question. Only time will tell.
