Fatah/Hamas is anti-Israel, yes. So much so, that it has gotten itself into trouble with several groups of Sunnis by running to the Shiites—perceived as being stronger—for help (e.g., Syrian-made missiles that Iran tried to export to Hamas—captured by the IDF). It’s common knowledge that Iran has supported Fatah/Hamas on a number of occassions as Saudi support for Hamas diminished. Hamas recently even got itself into trouble with the Egyptians again. As for Russia, Russia supplied and fomented the Six Day War, and Russia has obviously been up to its old tricks again without interruption except for its short term economic problem during the ‘90s.
Perception when it comes to Egypt. Remember all those people in Tahrir Square chanting “To Jerusalem we go, martyrs in the millions”? They were not all Muslim Brotherhood and/or Salafists by far.
