Forget what the Western media likes to report. When the US reduces a Middle Eastern country to rubble , they are thinking more of long-term strategically countering the likes of the Asian giants, China and India, than serving the interests of a small country like Israel and countering Israel's Arab and Persian enemies.
When the America's proxy Saudi Arabia, bombed Iranian backed Houthi rebels in Yemen with British arms, the West/America was thinking just as much of denying access of the deep-water Yemeni port of Aden to Indian and Chinese navies ,than keeping Iran and her allies in check.
Looking long-term at the bigger picture ,to the east of the Middle East, China and India , will develop powerful navies that will try to achieve maritime denial capabilities in the Arabian Sea and Indian Ocean. This might potentially shutting down the supply of gas and oil from the Arabian Peninsula.
That is why it was critical than Libya and Syria lying next to the Mediterranean ,in the western part of the Middle East., had to be destroyed so that long-term they could not be used as bases for ,say, Chinese forces , to stop supplies of Middle Eastern gas and oil to the West.
edit: yes, wrong thread. But since a few posters are bringing Israel up and comparing it to India.
