Former Polish president Lech Walesa said this week that he will soon host his own television showabout fishing. Walesa, a blustery, fiery labor activist, led the Solidarity movement of shipyard workers in the 1980s. Their agitation is widely credited with launching the anti-communist groundswell across Eastern Europe that culminated in the fall of the Berlin Wall in 1989. Since retiring from politics, Walesa has struggled to find his proper role. While I fish, I will be talking about the current situation in Poland and elsewhere, Walesa said. I will be a tough critic.
