Guatemala did it in May 2018 and Honduras in June 2021. Cohen initiated a campaign among mayors in Guatemala to name streets in their cities "Jerusalem Capital of Israel". Until now, there are 34 cities in Guatemala, including the capital Guatemala City that accepted the challenge, making Guatemala the first country in the world with streets bearing this name.
