Many nations in the Middle East and Africa have been trying to limit the MB to no real avail. The MB (and similar organizations) fill the vacuum, politically, socially, economically, financially and medically, where governments fail. To a great extent, Hezbollah in Lebanon, Islamic Jihad (in every land), HAMAS in Gaza and the West Bank, MB in Egypt, ISIS in Iraq all start by giving the simple folk aid in many forms, then they build heavily weaponized armies. After that, they go Islamic Bonker Berserk and try to overthrow regimes. While Israel smashes the HAMAS in the West Bank, (thus saving the PLO Abbas from certain Coup d’etat), the POTUS may ask for Iran's help in getting him out of a disaster of his own making.
It is pretty amazing to see the current POTUS back them all the way...
