Trump's recognition of Jerusalem as the capital of Israel only makes things better for the Arabs. Israel will have to fund infrastructure improvements to bring 'east' Jerusalem up to par with the rest of the city. The Arabs will still use Al Aqsa, nobody is taking anything away from them.
It simply means that a 'Palestinian' state will have to have some other city as its capital, something that everyone knew was going to happen.
If the Arabs, who are running around like chickens with their heads cut off, would simply take advantage of the situation, we could have peace in a few months. But Abbas and ilk only know how to reject everything and threaten terrible retribution. That tactic hasn't helped the Arabs for 70 years. I wonder if they are smart enough to try something different? Probably not.
Abbas is no leader. He has squandered every opportunity to help the Arabs. He enjoys the prestige and money that comes with the job, nothing more. He jets around the planet talking to world leaders who politely smile at him while ignoring everything he says.
Trump's declaration of recognition is the first constructive step taken in 40 years. Now Israel can be magnanimous and give ground to the Arabs, as long as they act like human beings. But with Abbas ordering 'Days of Rage', I don't see how they will.
