“Russia’s capacity to export LNG is limited.”
It is only a fraction of its former total production, and those terminals (Sakhalin and Yamal) were built to handle separate supply deals with Japan and China. They are not surplus capacity laying around just in case, and they are of much lower total volume than the pipeline network to Europe.

Based on what? I haven’t heard of anything to that effect.
