What did russia do in response to austria declaring war on serbia?
how did it affect germany?

answer: in response to austria's declaration of war, russia, serbia's ally, began moving its army toward russian-austrian border. expecting german to join austria, russia also mobilized along to german border. the german, russia's mobilization amounted to a declaration of war. on august 1, the german government declared war on russia

the main reason the us senate rejected the treaty of versailles was because "european nations wanted to punish germany"
