What does this quote mean

"My great objection to this Government is that it does not leave us the means of defending our rights or of waging war against tyranny" - P. Henry

I'm not really sure on this one

P. Henry is saying that the problem with the government system is that it holds too much power and does not leave enough power with the citizens. If there were to be an issue which violated the rights of the citizens, they would not have the ability to defend themselves or change their government to one which better suited their needs.
