At least one world leader isn't worried about Godwin's Law.
[Mexican President] Peña Nieto attacked the "populism" of the Trump campaign, which he said sought to put forward "very easy, simple solutions to problems that are obviously not that easy to solve."
"And there have been episodes in human history, unfortunately, where these expressions of this strident rhetoric have only led to very ominous situations in the history of humanity," the Mexican president added.
"That's how Mussolini got in, that's how Hitler got in, they took advantage of a situation, a problem perhaps, which humanity was going through at the time, after an economic crisis.
"And I think what (they) put forward ended up at what we know today from history, in global conflagration. We don't want that happening anywhere in the world," Peña Nieto said.
