"Hamas-Israel: what scenarios after the war?

The attacks perpetrated by Hamas in Israel on 7 October were the first on such a scale to be carried out on Israeli territory. They caused the death of 1,400 Israeli civilians and soldiers, and the taking of more than 200 hostages by Hamas. This was an unprecedented shock in Israel, reviving the memory of the Shoah and the persecution suffered by Jews in the past.

"Hamas-Israel, War in Ukraine: what are the military lessons?"

On 7 October 2023, Hamas launched a surprise attack on Israeli territory. To date, this has resulted in the deaths of more than 1,200 Israelis (according to the Israeli authorities) and the hostage-taking of 150 people. On 8 October, Israel launched an air operation against Gaza that has already claimed more than 1,000 lives. Israeli Prime Minister Benyamin Netanyahu announced a ground operation involving the mobilisation of 300,000 reservists to recover the hostages and "eradicate Hamas". These recent events put the Israeli-Palestinian conflict back at the heart of the strategic stage. After nearly 75 years of conflict, the prospects for peace and a two-state solution seem more inconceivable than ever.

"The butterfly effect of world conflicts

Hamas-Israel, war in Ukraine, Afghanistan, Sahel... what are the consequences of global conflicts on the international balance of power?

The attacks launched by Hamas on 7 October led to a series of chain reactions, a kind of "butterfly effect", starting with the launch of an air operation against Gaza by Israel the following day. Reactions are also multiplying at regional and international level.

In support of this observation, the researcher recalls the means implemented in recent years to strengthen European security, and puts forward concrete proposals. In the light of recent events, he returns to these essential themes at the strategic debate organised by the IHEDN on 15 November.

"Louis XIV and the Royale, the Sun meets the sea
