Trump is leaving and Biden probably is not extremely keen on this BS embargo of Qatar. Therefore nice guy Jared is undoing what was done in a recent past.
If Trump were to remain at 1600 Pensylvania Avenue this most likely would not happen any time soon.
What it doesn't add up is that Al-Jazeera is still alive and kicking. Wasn't it one of demands of the UAE, or Saudi Arabia (can't remember exactly), that the "terrorists", that is to say, the journalists of Al-Jazeera were put on jail ? They were being to much of a inconvinience.
