A worrying thought. The Western sanctions are clearly not the deciding factor in the rouble crash, that accolade goes to the oil price slump, but they are undoubtedly a factor. So Moscow would want them lifted, but the political cost of simply backing away from their ill-starred and ill-considered Donbas adventure is likely to be considered too great. So, I cannot wonder if the temptation will be to escalate the conflict, possibly throwing in a brigade or two of troops. Why? Short-term, this means things get worse, but I suspect the West would think twice about serious extra sanctions, fearful of the risk of collapse and chaos in a fragile Russia. But, the calculation would go, it might be enough to force Kyiv to make a deal, which would allow Putin to claim success and withdraw from the region (keeping Crimea, of course), claiming peace with honour. This in turn could be leveraged to get the sanctions regime lifted or at least eased, hopefully providing a degree of macroeconomic relief. After all, the alternative would seem to be a frozen conflict and indefinite sanctions. So, will the Kremlin think short-term escalation may bring medium-term relief, as a better option to long-term sanctions? We’ll see if units around Ukraine start to be brought back to full operational readiness. Or if Strelkov comes back in from the cold!
