Strengthen the military in the short term
Your military will be able to produce more tanks, weapons, fighter jets, and defense systems than it normally would have. If Russia were to invade, they would still be able to win a conflict because they have one of the best militaries in the world, but your military will be strong enough to both lengthen the war and raise the costs of war. Even if the communist bloc was weakened, the military buildup may deter the Russians from invading. This military buildup would come at the opportunity cost of investing in your developing domestic industries.
You have chosen a mixed economic nationalist approach to developing your economy. Your infant domestic industries will be carefully planned and nurtured. However, they will not be shielded from international competition. Fortunately, your economy will benefit from your international economic relations through absolute gains and access to more markets and resources. If your industries do not lose out to global competition, then, over time, your industries will innovate and develop to the point where they also make relative gains in an open world economy. Furthermore, your membership to all of those institutions increased your linkages with the capitalist bloc. The US has fully committed to a security agreement with Chechnya.
Your choice to depend upon Russia for capital and cheap energy has resulted in a significant strengthening of your military. However, the long-term economic sustainability of your military growth is in question because of your dependency on Russia for continued investment and artificially low costs of production.
Recently, two states succumbed to the capitalist bloc's pressure and switched from communist economic systems to capitalist economic systems. This has emboldened Russia, who have cut off their unconditional loans and cheap energy supplies to you. Russia has demanded you pay them back in the short term and has threatened to use force if necessary. Still, you have made the Russian decision to invade Chechnya much more difficult because your strengthened military has significantly raised the costs of war.
The Russians decide not to invade Chechnya because your security guarantee with the American bloc and modernized military have raised the costs of war too high. Congratulations, you have successfully maneuvered through a potential crisis despite having to make some tough decisions between economic and military investment.
