Salvini didn’t even have to build a wall. From Jon Hall at fmshooter.com:

During an awards acceptance speech on Monday, Germany’s Angela Merkel called on the international community to “stand up” to “excessive populism and nationalism”.
Merkel’s desperate plea to “stand up” to the frightening boogey-man of nationalism comes on the heels of news that Italy’s migration policy under Matteo Salvini, the interior minister, has dropped migration entry by 95%.
Being awarded the Fulbright Prize for International Understanding, Merkel took her acceptance speech as a chance to lambaste President Trump and attack the growing tide of populism sweeping over Europe.
She thanked Germany’s “American friends” who rebuilt the country, and Europe, after 1945 but jabbed at Trump’s America first domestic policies, claiming that with “all the differences that one has” countries “need to talk with one another, we need meetings, encounters, lines of communications” to solve international issues.
Merkel added that nationalism was working for “the vested interests of others”and that she would never “tire of making a case for the strength of a multilateral, rules-based and values-based global order”.
