There has been progress, but it's not nearly enough.
Some of the progress has recently been unwound with, basically, the death of OECD's pillar two, the minimum tax. Exempting the U.S. makes it pretty useless. Pillar one, which was aimed at the largest companies in the world, is dead, because the U.S. won't adopt it.
There have been some steps forward and several steps backward as well.
