No, it's not just an opinion. We're seeing a specific action taken by the US president to impose very large, sweeping, simultaneous tariffs on all goods from multiple countries in a manner that no other president has imposed before. The only comparable prior example is the Smoot-Hawley Act in 1930, but that was mainly a creation by Congress, with Herbert Hoover reluctantly signing the bill since he knew it overreached. It then deepened the Great Depression. If US presidents imposing sweeping, multi-country tariffs on all goods were part of a natural cycle, we'd be seeing Trump-level tariffs being imposed by just about every US president in the past. That hasn't happened before--at most, previous presidents have imposed targeted, singular tariffs on specific countries, and on specific products like steel, to achieve specific strategic goals. So by definition, what Trump has just done is not part of any previous natural cycle.
The other world issues you mention aren't at issue when discussing specifically whether tariffs imposed by a US president are part of a normal cycle. The fact that Trump's tariffs can be characterized as "an occurrence" doesn't make it a normal occurrence, since not everything that occurs is normal.
