Governor Scott Walker is inviting Israeli Prime Minister Benjamin Netanyahu to Wisconsin. And he’s inviting Israeli water firms to do business with the state and help Milwaukee area water companies grow. Walker is wrapping up a trade mission to Israel, where he met for an hour with Netanyahu on boosting the state’s ties. In a conference call Wednesday, the Republican Walker said the “hot spots” for water science are Israel, Indonesia, the Netherlands, and Milwaukee. Wisconsin water leaders and the state’s job creation agency joined Walker on the trip, seeking to bring some Israeli knowhow to Wisconsin companies — and the governor is due back in the state tomorrow (Friday).
