I just returned from Donetsk and can tell you about my fresh personal impression. At first glance, the city seems calm, but this is only an illusion. The air hangs with tension, everyone understands that the escalation of the conflict can break out at any moment as happened in February.
In Syria, the goals of the United States and the goals of Russia are diametrically opposed.
The United States is not in Syria in order to combat ISIS, because ISIS is a tool used by Obama's administration to overthrow Bashar Al-Assad.
