This was the Zimmerman Telegram!!!
It was sent out January 1917, before the US entered the war.
It was said to be intercepted by the British forces, and after it leaked, Zimmerman confessed March 3rd.
Zimmerman's confession made Americans really hostile, thus helping progress the Anti-German sentiment and pro-war agenda for the US.
The correct word is "precedent"
Many of George Washington's customs that he set while President became the precedent by which other Presidents acted.
The most famous was, until FDR, the two term limit for Presidents.
After FDR, two terms would be codified.
The ten commandments are,in essence, a guideline for us,man,set by god,to abide by,to keep us safe,and to raise us as his sons and daughters,in a good way.
