Good article.
He makes another good point about American support for one Islamic faction or another in hopes that they’ll wipe each other out. This has been a disaster for us, but it didn’t start with Obama or even with Bush. Our policy for 30 years or more has been to pick a faction that we regard as a minority counterbalance to the Islamic majority of an area (that is, Shiites vs Sunnis, for example) and think that they will fight each other to a standstill.
The only time that works is when you have a dictator, such as Assad or Saddam, who keeps an iron hand on the opposition Muslim groups and is ruthless in suppressing them. The only thing any Islamics understand is superior force.
But most of all, what the US and the West don’t understand is that as much as they hate each other, all of these Islamic factions hate us more. And when necessary, they are perfectly willing to work together against us.
