Capitol. @never a jw you should really think about talking to someone about your self harm over spelling errors:).
Actually it's much more complex. Jerusalem is one of the oldest cities in the world and has changed hands many times over 5000 years. Jewish settlers came in and pushed out Muslim Arabs in the 1920's I believe. Somewhat similar to the founding fathers of USA pushed out Native Americans to only portions of land. In Simons example the Native Americans could try to lay claim DC as their capital (sort of see below) and that would never happen.
Both Muslims, Jews & Christians have religious ties to Jerusalem. There isn't a simple solution. Some don't like the Native American comparison but it's really the closest one can come. Basically it's a minority/majority switch back in forth of population/rule over 5000 years until about 1920's then Jews became more dominate and laid claim.
I wish it were simple but it's not. I hope they can find peace there either by a two-state or a one state solution where Palestinians can move freely as they wish along with their jewish neighbors peacefully.
Peace is always good. I don't condone the violence but I acknowledge that frustration boils much like some of the exjw's burst into KH's, picket assemblies or yell at cart witnesses. I know I know those are not violent but they are both born out of frustration of not being listened to and that is what I'm talking about.
As for Trump recognizing Jerusalem thats really not a new stand as I mentioned congress passed that in 1995. It just hit 6 month waivers in order to help facility peace between Palestinians and Israel which I think everyone feels would be great everyone has tried including Trump admin, but history shows why it's not so easy:(
