The problem with the U.S. acknowledge Jerusalem as the capital of Israel is that it upsets an already-tottering balance in the Middle East that will further push the more people into extremism that will lead to more violence, and it's entirely unnecessary.
Jerusalem is the capital of Isreal, I'm with niko, *** them. Are we going to start basing all our decisions of off what muslim extremists believe? Better tell your wife to cover up.
I'm not concerned what the current extremists think. I'm concerned about creating more extremists.
If they were all already extremists, I'd be okay with Plan Glass Hole In The Desert.
This will have all of exactly zero effect on extremism, especially since extremism isn't something the US or Western nations "create", it already existed. How those various extremist organizations work is they have supreme leaders with unchecked authority supported by violence and religion. They then prey on a local uneducated, disillusioned, vulnerable and gullible population to convert them into soldiers. Those religious leaders can and will use any reason, real or imaginary, as material for recruitment and propaganda to support themselves. Because the population is uneducated and vulnerable the extremest leaders don't need a legitimate reason.
You want to know what created all that mess out there, it was Presidents Bush and Obama toppling the semi-stable governments that held things in check with the only tool that works out there, raw authoritarian violence. When the populations are that uneducated and vulnerable, the only thing that works is authoritarianism backed by violence for the simply reason that the population simply doesn't care about anything else. Pull the lynch pins out and suddenly you have dozens of local tribal warlords fighting it out over who's going to be the next authoritarian despot lynch pin. When a foreign nation then tries to get involved in that process all that happens is the tribal warlords turn against that foreign nation and attempt to expel it before returning to their original Game-Of-Thrones death match. ISIS is just a bunch of those same warlords getting together and deciding their best option to beat out the foreigners is to team up and form a cohesive entity that is far more effective as a military then dozens of smaller entities.
My personal opinion is that the US needs to get the *** out of the middle east and let the cards fall where they fall. Write this lesson down on giant stone tables and put the outside the White House, Congress and the Pentagon as a monumental reminder of what the *** not to do.
