This is so factually incorrect its blatant racist propaganda.

Hamas is a political party that electorally seized control of Gaza in in 2006 from Fatah, Yasser Arafat's party. Fatah rebelled against Hamas in 2007 and lost. Yet Fatah is still has 45 seats to Hamas' 72 on the PLC.

Nice little excerpt for you: https://en.m.wikipedia.org/wiki/Battle_of_Gaza_(2007)#2006_Palestinian_legislative_election

The Palestinian legislative election took place on 25 January 2006 and was judged to be free and fair by international observers.[18][19] It resulted in a Hamas victory, surprising Israel and the United States, which had expected their favoured partner, Fatah, to retain power.[20] On 27 January, US President George Bush said "the landslide victory of the militant Islamic group Hamas was a rejection of the "status quo" and a repudiation of the "old guard" that had failed to provide honest government and services".[2]

That last line from Bush is surprisingly correct. Hamas is effectively the Palestinian branch of the Egyptian Muslim Brotherhood. Their primary tactic is actually charity work by feeding the abundant poor people of Gaza and radicalizing them from there.
