Rubio is not averse to war, that is a problem.
At some point many to most are not averse to war and there are several ways to fight a war and there will be wars until He comes. When it comes down to it there is always war in the world because there is some godliness in the godless world. Rubio's statements in part reflected the fact that there is a war going on against criminals and against certain ideologies of what the US is, was and will be. Part of our internal pain will be establishing or reestablishing the ideology of what "Great" means. Speaking for myself, internally I'd like to see the efficiencies and competencies established and then weighted towards the DOJ and law enforcement to wage war within and clean house and then be established at an effective level to keep it clean. IOW, we need to find our core values and standards again and fight whatever kind of war we need to fight to maintain them. In a matter of a generation+ we went from working to expose infiltrating foreign ideologies to having a gov't half+/- filled with them. We can't be surprised that we're now at war within. Trump.2 is a huge shift wherever it's going. IMO Rubio's no bs approach is just a sign of that shift and of an admin that now understands how bad that infiltration became.
