Watching the Brasilian national news tonight, an intense international dispute between Ecuador, Columbia and Venezuela is treating to spill over into a war.
Brasil borders all three countries and has been called in by the Organization of American States to intervene and hopefully avoid hostilities. Ecuador and Venezuela have already sent troops to both borders of Columbia and are threatening to attack at any moment. Should that happen, it would spill over into Brasilian territory.
Though Brasil would not be involved in an actual war, it would have travel ramifications to and in the north and northeast of the country because of the proximity to what would be the war zone.
This trip is promising to be quite a ride!
