How to use "weaken" in a sentence

I ask, is it unconstitutional for a policeman or for a soldier to tender his resignation when he knows that he is called to serve a Government which traduces his own countrymen? Is it unconstitutional for me to go to the agriculturist and say to him "it's not wise for you to pay any taxes, if these taxes are used by the Government not to raise you but to weaken you?" I hold and I venture to submit, that there is nothing unconstitutional in it

It would be wrong of them to live and weaken the others.
