It's not particular to the US. The US is doing this by pressure as a compromise because the European powers threatened something worse. The US would prefer to change absolutely nothing and let its major corporations continue to avoid taxes where they can internationally.
Germany and France are overwhelmingly supporting this, because they benefit from damaging competing nations that have lower corporate income tax rates (eg Lithuania, Ireland, Hungary, North Macedonia, Montenegro, Romania, Serbia, Switzerland, Albania, Armenia, Bosnia, Bulgaria, Croatia). Both Germany (30%) and France (26.5%) have higher corporate income tax rates than the US and stand to benefit more by forcing the rest of the world to a higher base and or otherwise preventing any further decline in rates. This helps those two nations re-level Europe to their advantage, and stop any further race to the bottom on rates (where Germany and France can't follow).
For those two nations it's a particularly relevant matter in Europe. They've watched as Ireland has rapidly become one of the richest nations in world history by leveraging a very low corporate income tax rate. Ireland is taking economy, growth, away from them. In the time that Ireland's GDP per capita has massively exploded higher, Germany has seen a GDP per capita decline over 26 years. Read that again. 26 years, an inflation adjusted GDP per capita decline ($31.6k in 1995; inflation adjusted that's $57k today; their present GDP per capita is around $46k). A generation has been nearly lost to economic stagnation in Germany. France is in the same stagnation boat. And how has Ireland's GDP per capita performed in that time? $19k to $84k; an inflation adjusted 150% gain roughly over 26 years. Yeah. Now you understand what's going on - it's about knee-capping countries like Ireland, stopping their incredible climb.
Ultimately this corporate income tax rule is a regressive attack by powerful nations on typically poorer, weaker or otherwise smaller nations. It dilutes a substantial means for them to compete to draw capital.
France and Germany on one side. All those other nations I listed before on the other. It's quite obvious what's going on.
