If he is really as the letter portrays him and his people genuinely feel similar, then his best course of action is to remain abroad as a symbol for liberation.

Has Israel ramped up bombing?

An interesting thought -- Could Israel (and all the other rat intel agenices, basically the cabal) have staged this terrorist takeover as part of the larger plan of "Greater Israel"? Maybe in with Turkey as they stand to gain the Kurdish North (who they would love to genocide)? Israel uses the cover of 'terrorist groups' to bomb them into the stone age and then a 'peacekeeping' force, instead of outright conquering a sovereign nation.
