One question - Libya's and Egypt's goverments adopted this deployment??? If so - what questions may be???
Libya barely even has a government, and Sisi wants to have an arms dealer with even less scruples than the west.
As weak as they are - they are recognized by UN AFAIK, and thus have every right to invite anybody (including Russians) without asking for US permission.
Sadly this. I'm nobody's idea of a Russia apologist on this forum but Libya (and Egypt) are free to entertain friendships with whomever they please.
That said, whether the USA should maintain the current level of support for these two regimes if they cozy up to Moscow is a different question entirely
If being friends with Russia will encourage the United States to stop dealing with them, I would only hope that every Middle Eastern country becomes friends with Russia. Then we could finally leave the region once and for all.
