Germany with Russia allied with France conceived a war plan to rapidly defeat France before the superior resources of these two countries could be brought to bear on Germany. Because the French had heavily fortified the border, the German Schliffen Plan called for a massive stike through neutral Belgium to avoid the French fortifications along the French-German border. The Germans invaded Belgium (August 4, 1914).
this part is what gave Germany 'that' beginning aggressor title' ----This horified the world because it was correctly seen as the Germans trampeling the rights of a small neutral coutry in violation of international law. Thus from the beginning the Germans were seen in American and other countries as an unprincipled aggressor in the War. -----
did you read that ?
More importantly at the time, the German invasion brought Britain into the War (August 4, 1914). Britain had understandings with France and Russia, but there were not firm treaty commitments. Britain had guaranteed Belgian independence in the Treaty of London (1839). Britain may have entered the War anyway,
(and it probably would do just that due to economic rivalry etc) but it was the invasion of Belgium that triggered the British declaration of war and the dispatch of the British Expeditionary Force (BEF) to stop the Germans. The Germans gambled that they could defeat the French quickly as they did in the Franco-Prussian War. They disregarded the Belgian Army and calculated that they could defeat the French army before the British could deploy a substantial force to aid the French. Te Belgians put up and unepectedly stiff resistance, slowing the German advance. King Albert I proclaimed, "Belgium is a nation, not a road." The BEF although at first small also slowed the Germans. A Russian offensive forced the Germans to divert forces from the drive on Paris. In the end the Germans were stopped by the Miracle on the Marne (September 1914). Although the Germans were stopped, they had overrun most of Belgium which remained in German hands for most of the War.

this is from a book. but I don't think I will say the source. because no one on here wants sources posted

it would be refreshing if someone could even 'copy and paste' a real paragraph stating that England was the agressor to start WW1 but it can't be done.
