The Israeli Administration under the leadership of Benjamin Netanyahu has resisted all attempts at an international deal to get Iran to abandon it's nuclear program, rather, it pushes forward a rhetoric that would escalate to a full fledged war.
Furthermore, Netanyahu has ignored the rights that the UN has given to the Palestine refugees and, rather than peacefully deal with the issue, Israel has unlawfully seized land from what would have been a separate Palestinian state.
Therefore, as a nation that supports freedom and equality for all people, the United States of America should cut ties with the country of Israel.
