Can you be anti-Israel without being anti-Semitic, or are the two so tightly entwined as to be inseparable?

The question arises after Minnesota Congresswoman Ilhan Omar said support for Israel in Congress is bought and paid for. It was not Omar’s first anti-Israel comment, and she did apologize after being tarred as an anti-Semite on social media. But is being anti-Israel actually synonymous with being anti-Semitic?
