(Why would Sisi have pushed for a united Arab armed force, then? That’s something that Nasser could only have dreamed of. Sounds like “beneficial crisis” to me.)
Why go after a conspiracy theory instead of what’s already happening on the ground? Sunnis are already fighting Iran-supported Shia in Yemen. That’s what the joint force is supposed to do. Now that Iran is getting the green light from Obama to be a nuclear power, the Sunnis are scared shitless, and are making noise about allying themselves WITH Israel against Iran. This is not idle chatter as words of support to Israel usually are detrimental to any leader who utters them in the Arab world!
That’s the same kind of reasoning that saw Saddam Hussein as a friend of the USA.
The big crowd in Tahrir Square in 2011, and what they were chanting, is no conspiracy theory. There will be no alliance with Israel when the opportunity of invading Israel as a bonus prize presents itself during a conflict with Iran.
