He denounced the open letter "The United States Must Arm Ukraine Now Before It's Too Late" signed by 20 prominent American supporters of continued hostilities.
McGregor said that new arms shipments could provoke an escalation of the conflict.
“The fighting has entered a decisive stage.
It's time to stop them.
Instead, the authors of the letter are trying to consolidate the failure, ”the military man writes.
McGregor believes that the continuation of hostilities could lead to a situation where Ukraine will lose access to the sea and turn into an area between the Dnieper River and the border with Poland.
Earlier, former US Secretary of State Henry Kissinger said that the prolongation of the conflict in Ukraine could lead to an escalation, it must be completed through negotiations.
According to the former adviser to the US Secretary of Defense, Colonel Douglas McGregor, the American intelligence services are aware of the doom of Ukraine due to the exhaustion of the army.
