The US helped Panama gain its freedom from Colombia. The US did this so that they could build the Panama Canal.

the canal
YES!
Panama is the only country the canal passes through. There was initially interest (a bit of which remains to this day) of building the canal through Nicaragua - there are three proposals being 'floated' around in Nicaragua currently to build a new trans-oceanic passing, but the Panama Canal only goes through Panama.

The people living in Panama held a revolt against the Colombians, who at the time owned Panama. The US quickly recognized them as an independent nation and thus discussed an agreement settling the use of the land by the US to build a canal.
