740.0011 Pacific War/848b: Circular telegram

The Secretary of State to Diplomatic Representatives in the American Republics

In view of developments the Department trusts that the Government to which you are accredited will take strong measures to prevent the use by the Axis powers of any of its communication facilities in a manner inimical to hemispheric security. It is this Government’s view that constant vigilance should be exercised to prevent representatives of the Axis powers from sending or receiving messages through fictitious third parties or so-called cloaking addresses.

The Department would appreciate a telegraphic report as soon as possible.
