If you still insist....

....that the UN has a useful role to play in international law, this post on the Counterterrorism blog should help disabuse you of the notion.

Ahmed Idris Nasreddin, and his international business interests, continues to provide a shameful example of the ineffective application of UN measures to curb terrorism financing. Nasreddin was identified and designated by the US Treasury Department and the UN Al Qaeda and Taliban Sanctions Committee in August 2002 as a financial supporter of Al Qaeda. This designation placed an international legal obligation on all countries to freeze his assets and economic resources and to ensure that no funds, financial assets or other economic resouces were made available to him, or for his benefit. All Countries were also required to prevent his entry into or his transit through their territories. see UN Security Council Resolution 1526 (2004).. These designations also listed a number of Nasreddin's business interests. The funds and resources of these entities were also to be frozen. But, despite these restrictions little has been done to put him out of business. A few of his bank accounts were frozen, notably in Switzerland, but no further steps were taken to close down any of his business activities. He continues to operate numerous companies and business ventures in Europe (including holding company ownership of a major tourist hotel in Milan) and around the world. And he continues to travel with little or no hindrence.

If the UN isn't going to do its job, then why should the US continue to foot the bill and provide space on our land for the organization?
