sorry if i'm wrong but, if i'm not your welcome
There’s many causes as to why there was a Cold War, but the main one that sticks out to me imo was the ideological difference - Soviet Union was a huge communist type nation which was solely dependent on socialism as opposed to the United States who were known as a liberal democracy so that alone spread some fire to the pot.. United States were upon democracy when Soviet Union was upon dictatorship
<span> The Mexican/American War was an armed conflict between the United States and Mexico that took place in 1846–1848. However, Mexico
refused to accept these as valid, claiming the border was the Nueces
River. U.S. President James Polk endorsed the Rio Grande boundary, which
incited a dispute with Mexico.
I hope this helped:)
