no-one has done the latter equation. Rather, there are (accurate) insinuations of crony capitalism.
It may be accurate to say that the WWP is (or was) _allied_ with Saddam Hussein, but remember that FDR was allied with Stalin (as was Churchill, that icon of the right). Alliances are often temporary, which means that the WWP may not be (and is probably not) a tool of Saddam; they'll find new allies in the future, perhaps someone even worse. Even the old CP wasn't a true tool of the USSR, since every time the latter changed its line in a major way, a major part of the CP's rank and file left the party. In practice, the CP's impact reflected the wishes of not only the leadership and its "party line" but also the wishes of the ordinary members. (Those who see the CP as a Soviet tool typically only pay attention to the leadership.)
My feeling is that any WWP pro-Saddam slogans, etc. hurt the movement. But so do alliances with the pro-capitalist Democratic Party. If the anti-capitalist globalization/anti-war movements end up promoting the careers of either tin-pot bureaucrats of the WWP or those of the DP operatives, the movements will be sunk.
