I normally don’t or shouldn’t make particular, targeted appeals to my friends in the USA on matters political. My themes are normally general commentaries, messages of support and overall condemnatory. The rest are left to your good selves.
Here’s one there, short and not so sweet, which originated from this news headline:
https://www.bbc.co.uk/news/articles/c4g31n4ey9go 
The expiration of the treaty is not news, and there has been, is and will, be much written about it.
My contribution is based on a warning out of History:
The Reinsurance Treaty of 1887 between the Imperial Powers of Germany and Russia, forged by German Chancellor Bismarck.
https://en.wikipedia.org/wiki/Reinsurance_Treaty    
In 1890 Bismarck was forced to resign by Kaiser Wilhelm II-

basically because the former was being smarter than the latter (sometimes a few words of flippancy are worth paragraphs of analysis). The Treaty due for renewal was allowed to expire in the same year. A number of historians of World War I cite this as a contributory factor in the growing undercurrents of mutual tensions and suspicions wherein the old diplomatic system failed to operate during the final crisis that erupted in 1914.
That war had a particularly messy ending with an absence of important formal national surrenders; only an jagged Armistice which allowed an extremist conspiracy to foster in Germany which in turn led to World War II. Not that there was much peace between 1918 and 1939.

With this in mind, the next time you have cause to write to any elected official you might want to raise the point concerning the recent expiration. 

Take care everyone
