Any bets on how long he will last?

President Trump on Wednesday selected Robert C. O’Brien, the State Department’s chief hostage negotiator, to become his national security adviser, moving to reconstitute his foreign policy staff even as he faces rising tension with Iran.

In choosing Mr. O’Brien to replace John R. Bolton, who left the White House last week, the president chose a Los Angeles lawyer who had impressed him with his work to extricate Americans detained by countries like North Korea and Turkey. But it is not clear how different his advice will be from his predecessor given that Mr. O’Brien previously worked for Mr. Bolton and has cited his hawkish views in the past.

Mr. Trump announced the selection on Twitter shortly after saying he would also “substantially increase Sanctions” on Iran after weekend attacks on oil facilities in Saudi Arabia that officials in Washington and the region have blamed on the Tehran government.

So let’s see, that’s Michael Flynn, H.R. McMaster, and John Bolton who all tackled this job and were fired or resigned because they could not control the petulant, ignorant child who thinks he is president.

The first one was fired in less than a month and then indicted; the second was fired after a year and two months;, and the third was fired or resigned — depending on who is telling the story — after a year and five months.

How long do we think this O’Brien character will last?
