That is very likely.
A lot of European tension was the result of German armament driving an arms race and a desperate hunt for allies.
And that, particularly the Naval part, was the Kaisers doing.
Absolutely. Germany had no logical need for colonies or for a Navy capable of threatening UK.
But Kaiser Bill wanted them, apparently for prestige and/or self esteem reasons, so Germany made an enemy of the British Empire and spent ungodly sums to acquire colonies it could not defend and a Fleet that was good, but not good enough to win.
