You’re getting your facts mixed up ... LOL ...
Obama supported the Muslim Brotherhood in Egyot, but not Hamas in Gaza. And subsequently the Muslim Brotherhood has been “tossed out” of Egypt (as much as they can) and their leaders arrested. And the Muslim Brotherhood President of Egypt was deposed and replaced by a military man from Egypt’s military (who is President now) ... and Obama opposed that.
Hamas in Gaza did back the Muslim Brotherhood in Egypt, which is why Egypt right now is coming down hard on Hamas. But Obama never backed or funded Hamas in Gaza. He did back the Muslim Brotherhood in Egypt.
In addition to the above ... the money you’re referring to is for humanitarian aid to Palestinian civilians, which the Israeli Ambassador to the UN said just a couple of days ago ... that Israel has no fight against the people who live in Gaza, but only Hamas.
The USA doesn’t give money or arms to Hamas, but the USA does give humanitarian aid to the People there in Gaza through agencies, such as UNRWA who administers the programs.
And Israel, who controls the good that go into Gaza (they have a blockade around Gaza) does let the goods that the USA sends in through UNRWA go through their checkpoints, as Israel has no problem with that.
What Israel doesn’t let go through their checkpoints or past their blockade are arms and war material going to Hamas.
I hope that clears it up for you now ... :-) ...
US law forbids the aid to Hamas that the US has been funneling into Gaza. Obama doesn’t care about the law.
ObM has strong-armed Israel into allowing hundreds of millions of tons of concrete into Gaza from Israel’s own Nesher Industries.
It is no accident that the tunnel enterprize really took off 5 years ago, when the US gave Hamas $900 million.
