For the third time since the war began, President Roosevelt has warned the Axis Powers that if they use poison gas in a desperate effort to stem the Allied tide of victory, the United Nations will bring "full and swift retaliation in kind" upon Axis munitions centers, seaports and other military objectives. "Acts of this nature committed against any one" of the Allies will be regarded as having been committed against the United States itself and "treated accordingly," the President promised. Here is sound proof that Roosevelt wasn't bluffing. At an Eastern arsenal, one small part of the Nation's huge store of gas shells, are ready for retaliatory action against our enemies.
