You don't need a warrant for purely foreign eavesdropping. Thats not what I'm concerned about.

You're apparently concerned that the phone calls of foreign agents, located outside of the United States are not protected when they call people within the bounds of the United States.

You may somehow not be aware, but when even domestic phone-tap warrants are given, they don't specify all of the participants in the calls to be monitored. In that case, and the previous case, if ANY of the participants of the call can be monitored, the calls can be monitored.

"You may somehow not be aware, but when even domestic phone-tap warrants are given, they don't specify all of the participants in the calls to be monitored."

In the case of the domestic tap, there was a warrant in the first place. In the case of the foreign calls, there was no warrant since it was not needed, but once a U.S. person becomes involved that ceases to be the case. As far as our government goes, U.S. persons are a treated differently than foreign ones.
