One of the most interesting points is that the biggest battle was fought two week after the treaty was signed!
Once you know your enemies true ambitions then knock 'em back until they "can not" fight anymore. We didn't do that in Korean, Vietnam, Libya, Iraq ect. Hopefully we'll not repeat the previously failed strategies.
Not taking threats seriously, or finishing the job is becoming the American military tradition.
Did America neglect any warnings before the British invaded in 1812? Were we taken by surprise?
