I am not sure about this, but my guess is that Turkey is the second strongest member of NATO, after the United States.
Large =/= Strong
Turkish military is big but it is not technically strong. Almost everything they have is bought. If a single screw comes loose in an aircraft for example they can not fix it! Even their primitive UAV (Bayraktar) which they advertise these days is an assembly line which they have to import all the parts and just assemble it in Turkey.
I don't think that a majority of the NATO members would like to lose Turkey from the alliance. If the choice is going to be between Sweden and Turkey, then I am sure that it is going to be the latter.
The problem with Turkey is not over Sweden/Finland thing, that's just drama for the media. The problem with Turkey is how they are helping Russia. They have to do it too since Turkey is caught in the middle between East and West and can not face either side alone.
On the topic of Russian Gas replacement, France is playing a very dangerous game that could lead to oil prices shooting up again. They have been selling weapons to Arabs who are planning to resume attacking Yemen to steal Yemenis gas then export it to starving Europe.
The only problem is Yemen is not going to stand idly by, they are going to hit back hard, possibly their energy related infrastructures like before. It seems like they've forgotten what happened to Aramco and how they still haven't been able to recover the 4-7 million bpd capacity they lost.
Russia would also be screwed if this happens, so they may get involved also. There are already growing ties.
If the tensions resume again in that region, oil price could go back up above $120 and if they hit Arab's energy infrastructure we could be heading towards $200+ this time. But also that may bring NATO into that conflict since there is a good chance that Yemenis would also start targeting French forces.
I wonder what's going to happen to Europe's economy when Suez Canal is shut down blocking all trades with EU...
