and therefore allowing them to carry out their own imperialistic aggressive invasions around the globe
So says the ignorant Musket spouting shit he has just made up.
Here is an historian.
Contrast and compare.

Dr. Gary Sheffield.
" popular opinion: that the issues were not worth the ensuing bloodbath. Most modern scholars would not agree. Germany and Austria-Hungary (the Central Powers) are seen, at the very least, as creating the conditions for conflict. Some go much further, blaming Germany for planning and waging a deliberate war of aggression."

" Germany was ruled by a military dictatorship that sidelined the constitutional leader, the Kaiser. An Allied victory led to the maintenance and even extension of liberal democracy in Europe. A German victory would have snuffed it out. When the German army appeared to be on the verge of victory in spring 1918, the Kaiser crowed that this was the vindication of monarchy and autocracy over democracy."
