How embarassing for you. The ICC exists because other nations likewise retain their sovereign rights to sign treaties. The ICC is chartered by those treaties and valid on the sovereign soil of those signatory nations.
As a nation that respects national sovereignty, clearly there is nothing that we would want to do to change the rights of other nations to involve themselves in their own mutual treaties.
But the U.S. is NOT a part of the ICC due to Bush (contrary to your claims), and not only that, but Bush has convinced other nations to even grant exceptions to the ICC (for Americans - e.g. soldiers vacationing) for Americans while we are visiting those sovereign soils on which ICC treaties are valid.
Sure, the ICC exists, but it isn't valid in America and Bush has furthermore obtained exemptions for Americans even while in those countries which have signed onto the ICC treaties.
