Article 20 does more to improve U.S. ability to collect intelligence and protect its territorial waters than it does to impair it

The specific argument that the convention would pre- vent the U.S. from using its submarines to collect intelligence is fallacious. Several sources, including the minority views in the Senate Committee on Foreign Relations, note that Article 20 of the convention requires submarines and other underwater vehicles to navigate on the surface and show their flags when engaged in innocent passage. This is correct, so far as it goes. But the minority report then concludes that this would not especially during the Cold War—in gathering intelligence close to foreign shorelines.
What the minority report and other critics fail to men- tion is that the 1958 Convention on the Territorial Sea and the Contiguous Zone, to which the United States has long been party, contains exactly the same restriction.15 Moreover, the collection of intelligence in any guise within the territorial sea does not fall within the ambit of innocent passage. The United States would never accept foreign submarines or foreign warships engaging in intelligence-gathering operations in the ter- ritorial sea off of San Diego or Norfolk. Indeed, when President Reagan signed a proclamation extending the U.S. territorial sea to 12 nautical miles on December 27, 1988, consistent with the convention, one of the first things that the Coast Guard did was to advise a Soviet military vessel gathering intelligence just a few miles off of Pearl Harbor to leave the area immediately.16
The U.S. military and intelligence communities are well aware that the convention would have a positive impact on our national security. Moreover, as Senator Richard Lugar, at the time of this writing, ranking minority member of the Foreign Relations Committee, has argued, it would be unprecedented for the Senate to deny to our nation’s military and national security leadership a tool that they have unanimously claimed that they need, especially during a time of war.17
Opponents of U.S. ratification of UNCLOS have argued that U.S. intelligence operations will be complicated by UNCLOS because it will prevent U.S. submarines from gathering intelligence in territorial waters. However, these operations are already regulated by the existing 1958 convention which the U.S. ratified and expects other nations to abide by. Furthermore, the intelligence community has reviewed the treaty and concluded that it was still in U.S. interests to ratify the treaty.
