Hafter forces give Egypt the green-light to intervene on their behalf
This is the latest of Hafter’s several multi-year bids to take over Libya. A military dictatorship themselves, the Sisi junta has backed Hafter heavily, seeing it as a chance to install a friendly government on their border.
Egyptian airstrikes are common, but a direct ground invasion is hugely risky, because Turkey already has troops in Libya, and they are backing the alternative government in Tripoli. This looks tailor-made to be a proxy battle over Libya.
Egypt and Turkey have ideological differences, not just that Egypt is under military rule after a coup while Turkey’s coup failed. The two both have interests in the future of Libya, Turkey for the sake of oil and gas exploration.
It could be regionally complicated, as the Gulf Arab states generally back Egypt, and Hafter, and generally do not back Turkey. The US also tends to favor Egypt, but Turkey is a NATO member, and Egypt is not.
