...While McMaster’s appointment does not increase the number of generals in the top ranks of the administration—since he replaces General Flynn—his elevation to head the NSC could well signal a shift in the foreign policy orientation of the Trump administration, and represent a concession to the anti-Russian campaign being waged by the intelligence agencies, the Democratic Party and sections of the Republican Party.
...The appointment has special significance in terms of policy towards Russia because McMaster has been engaged in a major military project to study the conflict in Ukraine and the lessons to be drawn by US military planners preparing for war in Eastern Europe against the Russian army and air force. He said in 2016 that the Ukraine conflict has “revealed that the Russians have superior artillery firepower, better combat vehicles, and have learned sophisticated use of UAVs [drones] for tactical effect.”
According to a report last year in Politico, “McMaster is quietly overseeing a high-level government panel intended to figure out how the Army should adapt to this Russian wake-up call.” He told a Senate committee, “Russia possesses a variety of rocket, missile and cannon artillery systems that outrange and are more lethal than US Army artillery systems and munitions.” He called for developing advanced weapons to replace the two main Army armored vehicles, the Abrams tank and the Bradley Fighting Vehicle.
This background suggests that McMaster will be aligned with Secretary of Defense Mattis in viewing Russia as the main strategic adversary of US imperialism in both the Middle East and Europe. That accounts for the widespread praise for his selection by those who have been spearheading the anti-Russian campaign on behalf of the US military-intelligence apparatus.
