Providing them with state-of-the-art automatic weapons
Why would Israel do this?
1. To make money
2. To support its ally the US in destabilizing the Ukraine, a country on Russia's border
3. To foment anti-semitism so they can forever assume the "poor victim" role
They're playing a dirty game that allows them to "win" in multiple ways.
From a July 9th report by Haaretz, an Israeli news paper:
A group of more than 40 human rights activists have filed a petition with the High Court of Justice, demanding the cessation of Israeli arms exports to Ukraine.
They argue that these weapons serve forces that openly espouse a neo-Nazi ideology and cite evidence that the right-wing Azov militia, whose members are part of Ukraine’s armed forces, and are supported by the country’s ministry of internal affairs, is using these weapons.
