Ask people right and left and you will get different answers, those on the left who agree with removing Trident will agree with Corbyn, right wingers will just use anything to attack him.
The situation is the Army is sworn to serve the crown and H.M. Govt. whoever that may be, whatever their policies are, end of. The Military is not allowed to interfere by constitutional convention in politics, it is a line that can never be crossed. The military must never be seen to interfere in the civil democracy, we are not a military state. There are means and ways for the General to express his advice or concerns to Corbyn but to do it publicly is a serious breach of protocol and worrying interference by the military in the democratic process. I am shocked this could happen in Britain, if it happened elsewhere, we would cry foul about democratic rights.
We have to take the emotional politics out of the situation from left and right and have an investigation into this, personally I think the General should be held to account and forced to step down.
