Yes. That's a preferable alternative to fighting to be "top dog" in this worthless organization.
“Politics is the art of the possible.” That means that if we want to achieve more, first we have to set up the circumstances to make it possible to do it.
In this case, there’s no way Bush could abolish the World Bank now, even if he wanted to, because there are treaties and congress would not agree to abrogate them. Moreover, I very much doubt that Bush would want to abolish the bank, which means it could only be done with another president.
So, if you want to abolish the UN or the World Bank, that could only be done by electing a more conservative president and a much more conservative congress. Otherwise, it ain’t gonna happen.
And even if we succeeded, there might be more important things to spend the political capital on, such as appointing conservative judges, cleaning out our federal bureaucracy, reducing spending, lowering taxes, implementing a sane energy policy, fixing the immigration mess, fixing the massive Democrat cheating at the voting booths, and so forth.
