You are correct about Turkey’s rationale. And, it may be true. But, I don’t know and I don’t think you know about what Turkey is actually doing. President Trump has not exonerated Turkey and you shouldn’t either. If Trump has communicated a deal to Ergodan that he can go after the terrorists among the Kurds, as long as he leaves our allies among the Kurds alone (assuming there’s a difference), Trump is (again) being brilliant. I have been very impressed with Trump (and Pompeo).
Not a good move to defend George W. Bush by saying it was Tony Blair’s fault. This defense effectively admits that Bush, the President of the United States, was a dimwit. And, that Bush should have known it was stupid to Americanize Afghanistan.
I concur with most of what you posted.
I continue to believe that the final outcome will be a new nation of Kurds and Suni moslems to the north and east of the river. It will not include the agressive Turkish Kurds. It will include territory that was once IraQ and Syria
For fun a couple years ago I watched all the YT vids on combat in Afghanistan, most of which were by the BBC. I remember distinctly them mentioning how Blair convinced Bush to go for nation building as if it were a good thing, at the time.
