Interesting proposal from Luc Vancraen, an entrepreneur in Kyiv who holds a masters degree from Boston University:
If there is no Novorussia today it is because of the ferocious fighting of the Ukrainian armed forces. If the EU wants the Ukrainians to stop fighting after Donbas is liberated it will have to come up with a plan that convinces even the volunteer battalions that it is just a matter of time before Crimea returns to Ukraine.
The only way I can see this happen is through a Crimean Occupation Tax on all energy imported from Russia into the EU and all other countries that want to participate. President Putin will not like this tax at all but strangely enough it might be enough for him to belief that this could stop the Ukrainian army. It buys him time and he can speculate on convincing the EU to drop it later through good behaviour even though this won’t be easy with a name like this.
The tax will be paid on all Russian gas, oil and coal sold in the EU. Who pays this tax? Initially it will be EU citizens through their energy bills. This allows Putin through the Russian propaganda to trivialise these sanctions and to laugh with the stupidity of the EU that sanctions itself. But don’t underestimate the creativity of the energy companies. They will find other suppliers and this helps the EU to reduce dependency from a supplier they can no longer trust. Russia will be faced very fast with a serious dilemma. Lowering energy prices to include the tax so that it remains competitive with suppliers that don’t need to pay this or totally losing the biggest customer on earth. Simulations show that after just two years it is Russia that is paying this tax to avoid totally losing the EU as a customer.
