A few quick options if anyone is interested
I don't hate "(proclaimed)" but I see the concern. At least two other editors are against it.  
I love "(most countries maintain their embassies in Tel Aviv)" but this seems too long and could possibly only tell what not why. 
I'm also a big fan of "(positions on Jerusalem)". Thoughts? Is it a cop out? 
I suspect that "(disputed)" or anything similar (ie: "disputed by the international community")is a non starter.
Doing nothing seems to also not be an option for some even though I would not be completely against it since we already have an inline citation.
