Not unless you can control for all the other ills in the world, somehow. Weak evidence is just that; weak. Why not look at other things that happened in 2016 and draw equally valid conclusions? Eg, President Obama's presidency ended in 2016 when the results of the election were announced; the difference between his successor certainly changed national and international attitudes, far more than "man up" is a evidence-based practice that lowers suicide rates, anyway.

For any problem, there is an explanation that is simple, easy, and wrong.
