You've got that right. Reagan would be moving decisively, and hopefully with as much knowledge of the Russian mindset as possible.
Reagan would be moving to stop Russia, and doing some of the things that are currently being done except more, and more aggressive, all things that our Pro-Putin people oppose.
As it is, the pro-Russia people think that Obama is being too harsh, too threatening, too insensitive to the feelings of Putin (the current Russian president for life), as he is using his Army to make strategic wartime gains against us.
