Bottom line: while this might be fake news (it is Debka, after all), it is fully believable and consistent with available facts. Turkey has always been an issue as far as NATO membership and our operations in the region. You will recall that they initially were going to support operation Desert Storm -- allowing for the opening of a Northern Front -- but then, at the last moment, pulled their permission...and that was over 25 years ago, when there was a fully friendly government in power. With the current maniac, Sultan Erdogan, in power, the US government would be more than foolish to not at least have contingency plans in place to relocate operations immediately if and when needed.
Ain’t ‘buyin just yet, but a good thing if true.
