It is yet to be seen how it will affect the peace efforts in the region....
lol Because keeping the embassy in Tel Aviv has been such a big boost to "peace efforts" in the region. Officially, there is already peace between Israel and the Palestinian Authority and the only thing preventing Hamas and other terrorist groups from attacking Israel is Israel's military strength, not keeping the US embassy in Tel Aviv.
There have been no peace efforts since the 1990's. The focus of US and international diplomacy since then has been to create a Palestinian state, the so called two state solution which clearly should be renamed the two state delusion because there is no political entity among the Palestinians that can credibly offer peace to Israel and that means there can be no Palestinians state until there is. The proposition that the idiot Kerry offered that if not two states then there must be one state is, of course, nonsense. A population that is so hostile to Israel that it cannot be trusted to have a state of its own clearly cannot become part of the state of Israel. That means the status quo is the only viable solution until there is a radical change for the better among the Palestinian leadership, culture and population.
In fact, Trump's plan to move the embassy to Jerusalem and support Israeli communities in Judea and Samaria might be the wake up call the Palestinians need to give up their unrealizable aspirations and accept the fact they must make significant internal reforms before talk of a Palestinian state can be taken seriously.
