Generalized price increases of the type we’re having now is almost always due to one or more central banks. From Ron Paul at ronpaulinstitute.org:
The Biden administration and its allies continue to use Russian President Vladimir Putin as the convenient excuse for their economic failures. The most recent falsehood is that Russia’s invasion of Ukraine caused March’s 8.5 percent year-over-year increase in the Consumer Price Index (CPI).
Prices were surging long before Russian troops entered Ukraine. Furthermore, Putin did not stop exporting food and gas; it was the Biden administration and Congress that imposed sanctions, making US consumers suffer additional price increases. The blame for the economic effects lies with the US government, not Russia.
The United States has for years been meddling in Ukraine’s affairs with the explicit goal of moving US and NATO military forces ever closer to Russia. The most notorious example was the 2014 US-orchestrated coup that overthrew Ukraine’s democratically elected government.
