There have been many players in the Yemen war. Among them is an improbable player: Israel.
Israels Prime Minister Benjamin Netanyahu openly said in august: If Iran tries to block the Bab al-Mandab strait, it will find itself facing an international coalition determined to prevent it. This coalition will include all Israels army branches as well. That coalition had already been set up in 2015 by Saudi Arabia in partnership with Persian Gulf countries like the United Arab Emirates. Israel is also an unofficial partner. Israeli cyber companies, gun traders, terror-warfare instructors and even paid hitmen operated by an Israeli-owned company are partners to the war in Yemen. Now Yemen is being described by some observers as a mercenary heaven thanks to hefty sums of money paid to them by Saudi Arabia and its wealthy Arab allies.
