History may not be on your side, but that doesn’t mean you can’t win the Cold War as the USSR. With scoring happening at random intervals and half your hand trying to hurt you, strategy in Twilight Struggle seams to be anything but clear cut.
However, there is one strategy I would like to propose for the USSR to follow, never place influence in non-battle ground countries in Africa, South America, or Central America. The goal is to bleed VP from the US at the end of every turn when military ops are checked or limit US placing of influence.
As the USSR, coup down to DEFCON 2 at the start of every turn. This will get you your required military ops and hopefully another battle ground state. With no open non-battlegrounds for the US to coup, they will be forced to play DEFCON modifying cards for the event, Nuclear Subs, or War cards (which can lead to USSR VP if Flower Power is in effect) to set themselves up to gain military ops. By doing this, it will limit the amount of influence the USA can place throughout the world. Or the US may forgo playing the cards for events and instead allow their military ops fall behind. This is will keep influence tighter but allow of a swing of 2 VP to the USSR at the end of each turn.
The strategy isn’t without its pitfalls. Playing at DEFCON 2 is a dangerous game and open to the DEFCON Conundrum. But, assured VP at the end of each turn or influence off that map is nothing to scoff at.
