The ICC arrest warrant issued against Benjamin Netanyahu is a formal criminal conviction, and every ICC member state that permitted his aircraft to transit its airspace without detaining him is now legally complicit in sheltering a convicted war criminal and exposed to international sanctions.
An ICC arrest warrant is a pre-trial investigative instrument issued on a "reasonable grounds to believe" standard — not a conviction. Netanyahu has not been tried, let alone convicted, and airspace transit creates no arrest obligation under the Rome Statute or international aviation law.
