The severing of relations between Qatar and the Arab states, led by Saudi Arabia and Egypt, on the grounds that Qatar has been supporting terrorism, which follows on the heels of President Trump’s visit to Saudi Arabia, will have serious regional implications. Closing Qatar’s sea and air space and the land border with Saudi Arabia are tantamount to casus belli and could lead to chaos in the emirate if not solved soon. Isolating Qatar will also have serious regional implications on Israel and the Palestinian arena. Qatar is one of the main financial supporters of the reconstruction Gaza Strip, in addition to paying salaries within the Hamas government and helping to provide services to Gaza Strip residents. Its isolation could lead to a decrease in its support for the Gaza Strip and push Hamas into the open arms of Iran. Although fighting terrorism is in the interests of Israel and the United States, Israel would be wise to advise the US administration not to paint Qatar into the corner, if only because this would push it further towards Iran.
