I know you are afraid of the right, and we in the right are afraid of you.. but couldn't you just leave that matter be for some time, until the war with Argentina is over? Having those armies, the largest ones in the whole armed forces and the entirety of our fleet, away from the argentininan enemies but instead guarding the capital is something very ineffective for the war. I am not a tactician or a general, just a holy man, but I know that having 70% of our forces defending the capital from a unprobable coup isn't going to do this war any favours...
I am a military man though and am aware that the entire Argentinian army is one brigade. I honestly think half our commanders are timid to be afraid of such a small army. True we took a bruising last time, but they were stronger then and we had inept generals. That is not the case now.
