Germany or France didn't go to the Iraq war as a part of the "coalition of the willing", and said would vote against it in the UN. If Poland tried doing that to the USSR, there'd be a huge risk of Russian tanks in Warsaw and a government change. In fact, almost all major decisions Polish authorities made had to factor in the risk of Russian backlash and invasion. For example, they decided to institute martial law in 1981 and squash Solidarity, because they the alternative (Solidarity squashed by Russian tanks) would be much more bloody.
