Trade Deals Favorable to Europe & Japan Were Justified Following WWII for Rebuilding But On Into Today Ok?

Translate:

In addition to the Marshall Plan after WWII, the United States provided Europe and Japan revenue by allowing them to levy high tariffs on U. S. products imported, that was seventy years ago, and many of those high tariffs have remained, so are Europe and Japan really still rebuilding after seventy years of it?
