Well , that sub is pro-GNA and Turkey , so you can see what is their answer is
But i will explain , Erdogan was having a good relationship with Gadafi and Turkish companies were working fine in Libya .
Egypt is was having a bad relationship with Libya because of Gadafi ( he was attacking Egyptian always and when the revolution happened he blamed Egyptian in Libya ) Egypt also had a war between Libya due to Gadafi https://en.m.wikipedia.org/wiki/Libyan%E2%80%93Egyptian_War you will get lots of information from it .
When arab spring happened "to bring democracy" Nato , Qatar , UAE started to bomb Libyan army and destroyed it .
All the weapons that Gadafi owned has fallen in the hands of people , lots of heavy weapons .
No security or military to secure the boarder , lots of weapons got snuggled to Egypt , some went to sinai and some crossed to Gaza .
Qatar and UAE supported different factions with the same goal to throw Gadafi -like what they did in Syria- after throwing the Gadafi interested got crossed , everyone want a piece of that cake.
UAE , supported Bedouins with Hafter (who was agenral in Gadafi and then got kicked to USA then came back)
Qatar and Turkey started to support islamist (their always allies)
Qatar and Turkey also supported MBH in Egypt and gave them loans and Turkey sent garbage Trucks for morsi , Qatar helped by the media and giving them money to pay by sugar and cooking oil and win the election .
When people pushed to the streets aganist MBH in 30/6 immediately Qatar and Turkey supported them by media and calling protestors as anti-islam , Mubarak lovers ...etc
Then the military throw morsi to response to the protest and Sisi stole the show ,just like how the MBH stole 25jan , every faction of them have a huge support from a gulf country (Qatar vs UAE)
By the way MBH was cooperating with the military to get the power and throw the other parties in the dirt and they opposed them when the demand in 2011 the military to hand power to civilian .
Turkey, Qatar support the MBH with massive media the keep humiliate the military (which we love , but it different from the leaders we hate ) , and keep pushing that they are anti- islam and sisi is Zionist and his mom is a jew ....etc
They doing that not because sisi is a dictator (Erdogan and tamim is also dictators ) but they want the MBH back to power (their own puppets)
In 2015 isis slayed 21christian Egyptian in Libya and Egypt striked them with Jets with the help of both Libyan government .also the weapons kept coming from Libya and attacked on upper Egypt Christian , and the ambush of police convey that killed lots of young soldiers , and terrorist forced a bus full of copts to get down and killed them
Hatfar and Bedouin helped Egypt to eliminate the terrorist and secure the boarder , that's why Egypt sent them armored vehicles and light weapons .
Egypt supported Morocco deal and Alsaraj government , and hosted him in Egypt , but kept reminding him for eliminate the militants and help for establish a patriotic professional military
Alsaraj failed to even control his militants and once they surrounded his office .
Egypt didn't help haftar but UAE did sending them anti-air and expertise , finance , hiring mercenaries ...etc
Egypt didn't send any troops or experts or anti air or anything there , same as they did in Yemen
Even if Egypt has huge alliance with UAE but didn't help them in Yemen or Libya .
When hafter announce the march towards Libya , Egypt request peaceful and political solutions , and did sent or help him at all , only UAE and Russian vagner , and maybe franc
After the situation got messy and Turkey brought Syrian militants , also hafter have militants and large amount of weapons got pumped in Libya.
Egypt wants the fight to be away as possible to prevent all these militants with their weapons from coming close ، and keep them busy there .
Also Turkey wants to throw sisi for the MBH (not for democracy carp) and wants Egypt to side with Turkey and face Europe because Greece is taking Turkish EEZ .
Egypt won't go in trouble with Europe or anger them , it's already in bad security and economy situation , and the constant threat of instability specially when a 24 hours media from Turkey and Qatari attacking the military and wants a revolution .
