They had pledged to fight with other countries.

The assassination triggered Austria-Hungary vs Serbia, and a web of alliances and mutual-defense commitments (plus rigid mobilization war plans) caused Russia, Germany, France, Britain, etc. to enter quickly — not to prevent assassinations or on orders from the U.S.
