The symbiotic relationship between the philosophies of the two groups will be frightening to watch in the next few years. Of course, Hamas claims its roots are in the Brotherhood, not the other way around. But aping the tactics and organization of Hamas in order to deal with the outside world should cause concern in the west.
Gaza's Hamas premier was in Egypt Monday on his first trip outside the blockaded territory since the Islamists overran it in 2007, saying his meeting with his Islamic ideological mentors threatens Israel.
Ismail Haniyeh discussed Mideast politics with the leader of Egypt's Muslim Brotherhood, which has emerged as the biggest winner in the first parliamentary elections in post-uprising Egypt, capturing nearly half of the seats so far.
Hamas is considered an offshoot of the Brotherhood.
Brotherhood leader Mohammed Badie met Haniyeh at the group's newly inaugurated headquarters in a Cairo suburb.
"The Brotherhood center has always embraced issues of liberation, foremost the Palestinian issue," Badie said, according to Egypt's state Middle East News Agency.
He added that Hamas has served as a role model to the Brotherhood in its reconciliation with the Fatah movement and in closing the recent prisoner swap deal with Israel.
The Brotherhood renounced violence in the 1970s, but it supports Hamas in its "resistance" against Israel.
Hamas is considered a terror group by Israel, the US and EU, killing hundreds of Israelis in attacks, including suicide bombings. The West insists that before it deals with Hamas, the group must renounce violence, recognize Israel and accept existing peace accords. Hamas has refused.
The Muslim Brotherhood in Egypt has made noises about tossing the Camp David Accords which would set Egypt and Israel on a collision course. To use as a role model a hate group, a terrorist group, a fanatical, violent uncompromising militarist organization should wake up the west to the danger posed by a Brotherhood takeover in Egypt.
But will it?
