What strategy would be most effective in addressing entryism tactics of the Muslim Brotherhood? In the Arab world, several countries—including Egypt, the United Arab Emirates, and Saudi Arabia—have banned the Islamist Brotherhood. In the West, matters are more complex: the European and American branches of the MB deny any ties with the parent organization. This complicates legal proceedings against them, as was the case in 2017 when the Trump administration attempted, for the first time, to ban Tanzim al-Dawli, the international body of the Muslim Brotherhood. This did not prevent the U.S. president from renewing, last October, his intention to ban the Muslim Brotherhood. Several states, such as Texas and California, have also taken action, in last November and December, by banning the political and financial activities of the Islamist Brotherhood within their territories.

In France, the idea is gaining ground. According to this poll conducted by Ifop for ‘‘Screen Watch’’ (survey carried out in August and September among two samples: 1,005 people of Muslim faith and 1,000 people representative of the French population as a whole), 53% of the French population approve of banning the Muslim Brotherhood-affiliated organizations. Among Muslims in France, opinions are divided: 38% are in favor, 43% are opposed, and 19% have no clear opinion on the issue.
