I don't think NATO will become history by denying requests, it will become irrelevant because the background politics will result in requests never being made. It will die with a whimper not a bang...it will just fade away to nothing, an afterthought. It will fade away because Russia becomes more useful to France than does the U.S. Or Turkey - member states that are actually now a hinderance not a help. And when and if Russia forcibly exacts it's revenge on Turkey, not a peep will be heard from NATO...it will die from irrelevance.
Decades ago Turkey stood to benefit from association with Europe. It wanted to join Europe in the more prosperous, developed world. And I suspect NATO gave them plenty, in return for missile sites targeted at the USSR.
Today Turkey appears to have more in common with Islamic states, then with Europe.
So if Russia and France have common interests, and Turkey does not, why not let history march along, and why not abandon Turkey to the insanity of their region?
Turkey refused us help in 2003, and Turkey is against the Kurds. Why should we support Turkey?
