Personally, i think that the constitutional changes are beneficial to turkey in the long run as it would enable turkey to go all in on
Erdogan's neo-ottomanic ambition.
Geopolitically, they have stacked the deck in their favor with not one but two former territories (syria and perhaps armenia if they get support from Azerbajian) weakened and ripe for annexation.
They also have NATO to call in if their own army can't handle it, a powerful instrument indeed.
Aside from that they have the support of western europe wherether they like it or not due to the concentrations of diaspora either as their fifth column and in their governments.
Their only complications would be greece and their neighbors to the west, but as it stands now there is little that stops Turkey from become a member of the EU and tap into their markets as well.
Of course this is all conjecture, but it's hard to deny that Erdogan's ambitions are going exactly as planned.
