I have been saying this for a couple of years. The war in Syria is spookily similar to The Spanish Civil War which preceded War War 2.
Supporters of American, French, and British bombing in Syria at this time may exult that these Western powers are displaying their “balls,” but there is every probability that they will balls it up. They have made a mess of Syria since they involved themselves there in the vain attempt to bring down President Bashar al-Assad in 2011. Islamic State fanatics emerged as the dominant power within the anti-Assad forces. They are not anti-dictatorship so much as anti-minority, particularly the ruling quasi-Shiite Alawite minority. The Western powers tolerated ISIS’ crimes, until ISIS turned from its bases in Syria and seized about a third of the American protectorate of Iraq. It was then that the U.S., to save the Kurdish capital at Erbil and the national capital of Baghdad, first bombed ISIS positions. Since then, other countries, including the Russians who sought to save their Syrian protectorate, have joined the crusade against the Islamic State.
Do a little search of History and you will see how similar it is. Be careful.
