Instead of seeking peace, the German General Staff contrived the Schlieffen Plan and an army to carry it out.

The national anthem of Germany was „Hail to thee in victor‘s crown“, just as America‘s was „My country, t’is of Thee, sweet land of liberty“. The melody was the same 🙂
The Deutschlandlied didn’t become the national anthem until 1922, and „über alles“ was supposed that the whole country should be estimated as more than its constituent parts.

The German national anthem in 1914 was Heil dir im Siegerkranz, an ode to the Kaiser sung to the same tune as God Save the King.
The piece you're thinking of, the Deutschlandlied, was written in the 1840's as a plea for Germans to put national unification above everything else.
