The panama canal helped america and other countries by making the shipment of goods shorter then going under South America, and It helped America by having the countries paying tolls to get though the canal.
It may have caused problems but then it helped us in a way because when there was a war countries wanted us to be on their side and every war we had helped a country we have won.
The way WW1 was fought was out-dated because they were using tanks, gas, machine guns, rifles and mortars and If you were one of the men that charged then you most likely would have been killed.
In the past we had to be imperialistic to be able to survive in the world because then countries would fight us to try to conquer us and by fighting other countries it showed we were the country to beat.
In my opinion I think Theodore Roosevelt was the best president we've had because of all the laws he made like food acts and he helped majorly on the forest and national parks he saved the land from becoming a possible company or landfill.
I disagree because we fought the Spanish for land to show our imperialism we build the Panama canal to charge any country that chooses to ship supplies though.
I support you because the number of immigrants that come to America they are taking the jobs that Americans should have ,but the immigrants offer less money and work longer.
