This is probably the best part of the speech:

“Today we finally acknowledge the obvious: That Jerusalem is Israel’s capital,” Trump said. “This is nothing more or less than a recognition of reality. It is also the right thing to do. It’s something that has to be done.”

This is the actual presidential proclamation on Jerusalem:

PRESIDENT DONALD J. TRUMP’S PROCLAMATION ON JERUSALEM AS THE CAPITAL OF THE STATE OF ISRAEL

“My announcement today marks the beginning of a new approach to the conflict between Israel and the Palestinians.” – President Donald J. Trump

RECOGNIZING JERUSALEM: President Donald J. Trump is following through on his promise to recognize Jerusalem as the capital of the State of Israel and has instructed the State Department to begin to relocate the U.S. Embassy to Israel from Tel Aviv to Jerusalem.

• Today, December 6, 2017, President Trump recognized Jerusalem, the ancient capital of the Jewish people, as the capital of the State of Israel.
  • In taking this action, President Trump fulfilled a major campaign promise of his and many previous Presidential candidates.
• The Trump Administration is fully coordinated in supporting this historic action by the President, and has engaged broadly with both our Congressional and international partners on this issue.
  • President Trump’s action enjoys broad, bipartisan support in Congress, including as expressed in the Jerusalem Recognition Act of 1995.  This Act was reaffirmed by a unanimous vote of the Senate only six months ago.
• President Trump has instructed the State Department to develop a plan to relocate the U.S. Embassy from Tel Aviv to Jerusalem.
• Departments and Agencies have implemented a robust security plan to ensure the safety of our citizens and assets in the region.

STATUS OF JERUSALEM: President Trump recognizes that specific boundaries of sovereignty in Jerusalem is highly sensitive and subject to final status negotiations.

• President Trump recognizes that the status of Jerusalem is a highly-sensitive issue, but he does not think the peace process is aided by ignoring the simple truth that Jerusalem is home to Israel’s legislature, supreme court, President, and Prime Minister.
• President Trump recognizes that the specific boundaries of Israeli sovereignty in Jerusalem are subject to final status negotiations between the parties.
• President Trump reaffirms United States support for the status quo at the Temple Mount, also known as Haram al Sharif.

COMMITTED TO THE PEACE PROCESS: President Trump is committed to achieving a lasting peace agreement between Israelis and Palestinians.

• President Trump remains committed to achieving a lasting peace agreement between the Israelis and Palestinians, and he is optimistic that peace can be achieved.
• Delaying the recognition of Jerusalem as the capital of Israel has not helped achieve peace over the past two decades.
• President Trump is prepared to support a two-state solution to the dispute between the Israelis and Palestinians, if agreed to by the parties.

And there was this nonsense:

This is my take on the announcement as a non-expert on the Middle East.
1. It is significant. Were it not significant it would have a) happened much earlier and b) no one would care.
2. If anything, this helps the Middle East peace process. In a worst-case scenario, it has no effect. Several other countries, including Russia, already recognize Jerusalem as the capital of Israel. This move breaks the status quo and the fact that it is known that Trump supports Israel’s existing settlements, it can force the Palestinian kleptocracy to make a deal while they still have anything to deal with.
3. Any movement of the US embassy will require several years to acquire land, do the archaeological clearance necessary, and construct a facility that will be truck-bomb resistant. But saying that process will start is also significant.
4. Trump said he was taking no position on the actual borders of Jerusalem. (No Chuck Schumer, he did not declare Jerusalem to be undivided.) This is in keeping with various UN Resolutions on a “final status” of the city. But the writing is clearly on the wall that he probably won’t shy away from making such a declaration if need be.
