I'm not really optimistic about western Europe's willingness to absorb damage in it economy in order to damage Russia. France's government expenditures are 55% of GDP, much of it financed by borrowing. That's the level maintained by major powers in the world wars. Can the French state demand more from a private sector that's funding the equivalent of a total war?

Worse yet, western European politics gives you the strong impression all these expenditures are necessary to prevent the election of a pro-Russian government or a bloody revolution.

Hence why sanctions seem to be something of a joke.
