As far as I can tell this is ultimately window dressing, because what natsec means is that they want money for climate mitigation, not that they support international cooperation. The core of US natsec all about establishing and maintaining hegemony, and ideas of sacrifice for building international consensus are very foreign and absolutely not something that are growing in lockstep to these climate change statements.
@tobychev National security, in the US and everywhere, is dynamic - especially since the 'end' of the Cold War and 911. Leaderships have political agendas, but General Staffs' planners and strategists thesedays are very forward-looking and aware of the risks of climate change (and emerging and disruptive threats). National and allied (coaltion, partnership incl NATO) survival depends on addressing climate change. Military planners and generals know this. In a sense, they are our best hope.
