There was a need for a replacement of a World War, something that would level out the disbalances of the capitalist economy, revive it and still maintain the status-quo of the ruling elites.
The alternative to a shooting war would be a cold war, or, as it is preferred to be called today, a hybrid war. A hybrid war engages elements of finance, trade, psychology, information technology, cyber attacks, special forces against the enemy, but it does not give the rulers the authority to use command methods on the economy. And this is necessary for overcoming the dis-balances of the economy.
And here comes the coronavirus. The rulers started to blow up a threat, create an atmosphere of fear. Using the panic, the authorities are given unlimited powers and start actively to interfere in the economy.
