The problem of course being that he's lying. Other major countries that we have partnered with do not have as high of inflation rates as the U.S. I'm sure he figured he could lie about the inflation in other countries because his constituents don't care about the truth; we've seen this over and over again.
If the idea of his Administration triggering inflation was crazy, most economists wouldn't be agreeing that this is in fact the case. They of course say that Biden proactively going after coal and fossil fuel, jacked up fuel prices which impacted the costs on pretty much everything we purchase. He is ground zero for our inflation problems. If he had any credibility at all (which he doesn't), he'd admit this so we can move forward with fixes.
