First is Pat Buchanan dead? Everyone is using past tense.
Pat is/ was an isolationist and that led him to oppose anyone who wanted America to defend Israel. That in turn led him to, at the very least, be unimpressed by any Jewish causes.
And, there definitely was a side of Nixon which resented “liberal NY Jews”and saw them as a political enemy. Until they began to hate Israel, American liberal Jews were a very powerful political block.
I don’t support Pat on this I’m just explaining it.
Regarding WWII, it’s a fact the British mismanaged getting into that war, including declaring war over Poland, which the British could not help. But that’s a strategic issue, Hitler had to be stopped.
“isolationist”
Its hard to imagine a less useful description of the America First worldview in the age of Trump.
Buchanan doesn’t claim that the British “mismanaged” the war. He claims that Hitler was a peaceful man who was goaded into the war by Churchill. He basically calls Churchill a warmonger who foisted war on the innocent Hitler.
His over the top defense of the indefensible Hitler is why he is sidelined.
And yet Nixon saved Israel's bacon in 1973, Golda Meir even said so.
