I think the A4 will tolerate OTL Britain, France, the Netherlands, and Denmark having colonies or territories because those territories are just small patches of land that hold symbolic meaning (minus Denmark which has a U.S. Space Force base, Gibraltar being a sub base for the RN and allies, the Sovereign UK bases in Cyprus, and the Anglo-American base in Diego Garcia to keep the PRC, Pakistan, and Iran in check).
Brings back to how the Middle East was divided after WWI. Wahabbism and extremism didn't pop-up overnight. Depending how the A4 deals with the post-Second Global War Middle East, AQ and the Taliban won't exist. But we may have analogues to them or 1970s-80s terrorist groups. However, without Israel existing here, there will be no PLO.
