It has been a week that has seen the International Criminal Court issue arrest warrants for the Israeli leader Benjamin Netanyahu and his former minister of Defence Yoav Gallant. They are accused of war crimes and crimes against humanity in Gaza, alongside the Hamas commander Mohammed Deif.

The news was met with a furious reaction from the prime minister’s office, calling it biased, absurd and anti semitic. The impact of the warrants, will in part depend on whether ICC members decide to enforce them.

It has been a week that has seen the rules of the conflict change in Ukraine. After months of reluctance, US media reported that President Biden had relented and given permission for Kyiv to use American long range missile and strike targets deep in Russian territory. Britain and France appear to have followed suit, with reports that their jointly-made Storm Shadow / Scalp cruise missiles were used on Wednesday. But no out and out confirmation. The watch words: Deliberate Ambiguity. Russia responded. President Putin said it was a new type of intercontinental ballistic missile.

And in the midst of war in Europe and the Middle East, it has been a week where world leaders met in Latin America to focus on other threats to the planet. Global warming and World Hunger were the focus of formal talks at the G20 summit in Brazil. But it was in the corridors and briefing rooms that the dominant issue was made clear by diplomats. Preparations to deal with the man who wasn’t there, yet is impossible to ignore. Trump 2.0 on the horizon, and talk is of “transactional geopolitics, replacing consensus agreements.
