Under what principles of "conservatism" does one's own country support one particular other country in its tribal and territorial disputes with its own inhabitants and its neighbors?
There are none.
Israel is here to stay, the USA will ALWAYS support Israel, and the Left-wing cranks in Europe, the new Nazis, can just twirl on it.
The don't much like the USA either. Jealous losers. Same as anti-Semites.
