Some time ago, I came to the conclusion that the West could and would, at some point, no longer tolerate missiles coming from Russia and into Ukraine. It seems that the missiles are the only effective "army" Russia has. This could bring us to NATO soldiers in Ukranian fighting agaisnt those missile sites.

The stoppage of grain shipments is just adding to more tangible western involvement.

I like the link between North African oil and the grain shipments. Societies in a hunger revolt don't export much oil.
