Adnaan and Tor Stumo, the two Massachusetts men who were detained by Israeli forces while aboard a volunteer flotilla bringing humanitarian aid to Gaza, were released earlier this month. The same day they returned home to the United States, a ceasefire deal between Israel and Hamas officially came into effect. The brothers, who grew up in a political family, aren't new to activism, especially not for Palestine. Ralph Nader, a lawyer and political activist, is their great uncle.
