If you are in another country and want to help with US:
Set up trade deals with co-operatives in the US. This will help create more co-ops in the US, and offset the influence of the horrible corporate culture here. Current US politics are an extension of their corporate culture.

If you don't know him, I will recommend the very beautiful, haunting poetry by Wilfred Owen on this Veteran's Day. Glad to see others have an interest in him as well!!
I always think about my favorite poet on Veteran’s Day—Wilfred Owen, a soldier who died in combat, who saw terrible things & transformed them into urgent, horrific, & beautiful words.
because it is not “sweet & beautiful” to die for your country.

Oh look, it is possible to massive offshore deployments of seismometers after all!
Would *never* know it from how the US has been (not) instrumenting Alaska and Cascadia.
It's kind of like green energy: the US has behaved lackadaisically for 20+ years while other countries actually improve.

Kudos to the @seattletimes.com for spelling with diacritical marks used in the Hawaiian language, the ʻokina and the kahakō.
A few years ago, when I asked the NY Times to spell my affiliation as University of Hawaiʻi at Mānoa, they refused because it went against their style guide.
