In Israel, Twersky worked for the Labor Party's international affairs department, where he dealt with the Socialist International. He edited Shdemot, the literary journal of the kibbutz movement, and Spectrum, an English-language political monthly. Twersky served in an artillery unit during the 1982 Lebanon War.[1]
Twersky returned to the U.S. in 1986 and became a full-time journalist. When the YiddishForverts started an English-language edition in 1990, he became deputy editor and Washington bureau chief. During his seven years at The Forward, Twersky was responsible for breaking many news stories. One of his best-known stories involved President Bill Clinton's associate Johnnetta B. Cole, who had been suggested as a possible nominee for Secretary of Education, and the fact that she had served on the national committee of the Venceremos Brigade.[1][4] Another of Twersky's stories brought to light some views of Lani Guinier, a law professor whom Clinton had nominated to be Assistant Attorney General for Civil Rights; those opinions were considered controversial and her nomination was withdrawn.[1][4]
After leaving The Forward, Twersky became editor of the New Jersey Jewish News. Later he joined The New York Sun as foreign editor and columnist. Twersky also worked as director of international affairs for the American Jewish Congress.[1][3]
