The old definitions of right and left are being redefined. For example the left used to be anti-war, but now the right is anti-war (though not because they love peace, but because they are isolationists). As for the right admiring Xi, Putin and Kim, this ties in with the isolationism, they really don't care how other countries are run and they admire strong leaders. So, for the Maga people strong leaders are good and weak (Western Democratic) leaders are bad.
