Something to bear in mind and realise is a fact that is not fiction and fake news
DS999,
The best of companies/entities in that industry are always extremely careful of whom they do deals with ...... and the real money/wealth to made is in the selling of products and services to the likes of a Russia or NSO and not in the buying of them from them.
However, as you rightly say, putting pathetic sanctions on such parties as can render one catastrophically vulnerable to exploitation via their products and services is as effective as a warning to others in such fields as is the pain inflicted from a feather blow.
And aint that the gospel truth ‽ .
