Good question. I did some checking - I'll put stuff below. I see that they say they are "funded primarilyby member states. Wonder if George Soros is behind that vague sentence:
Who funds the court?
The ICC, as an independent body, is funded primarily by its member states. The contributions of each state are determined by the same method used by the UN, which roughly corresponds with a country’s income. Additional funding is provided by voluntary government contributions, international organizations, individuals, corporations, and other entities. The United Nations may provide funding if it is approved by the General Assembly and is related to a "situation" referred to the court by the Security Council.
What is the relationship between the United States and the ICC?
At the time of statute negotiations, the United States opposed the court, fearing U.S. soldiers could be subject to trivial or politically motivated prosecutions. After the establishment of the court, the United States insisted on immunity for all its military personnel operating in UN peacekeeping missions, particularly in East Timor and Bosnia-Herzegovina. This immunity was denied in East Timor. However, after increased pressure from the U.S. veto of a UN-extended peacekeeping mission in Bosnia-Herzegovina--and a threat to block future UN missions, starting with Bosnia, if the Security Council did not accept the terms of immunity--Washington was granted a one-year exemption from prosecution to be renewed every year, as a compromise. The United States also formed bilateral agreements with other nations obliging them not to hand over U.S. personnel to the ICC; in 2002, Congress passed the American Service Member’s Protection Act, authorizing the president to use all means necessary to free U.S. personnel detained by the ICC. Though former President Bill Clinton signed the treaty at the end of his second term, President George W. Bush withdrew the U.S. signature in 2002.
What other countries are not involved?
Seven countries voted against the statute: China, Iraq, Israel, Libya, Qatar, the United States, and Yemen. China objected on grounds that "the statute is an attempt to interfere with the domestic affairs of a sovereign nation." Other non-members include India, Iran, Japan, North Korea, Pakistan, Saudi Arabia, Sudan, Syria, and Turkey. While most Western European and South American countries are signatories, there are only two Arab nation members—Jordan and Tunisia. There are eighteen Asian members of the IC
