It follows if there was no U.S. President H.W. Bush Iraq war then no cause for Bin Laden 9/11 retaliation, no U.S. President G.W. Bush Afghan-Iraq war then no ISIL.
No horror wars with massive unspeakable refugee crises. No CIA torture reports.
Simple conclusion, stay home and mind one’s own business, respect other cultures and sovereign countries.
A just, leading, moral society as America wishes to be, is obligated to hold their own responsibility for crimes against humanity accountable.
Then there might be some peace on earth.
