Excellent short-book analysis
Format: Paperback
This short book is an outstanding analysis of how nations end wars, or accept peace. Ikle shows how governments often prefer obviously self-destructive courses rather then compromise peace terms. The problem is most acute when factional interests dominate strategy rather then a rational unitary interest. In such a circumstance, factions that benefit from continuing the war will accuse those pursuing peace of treason. Sadly, there is no equivalent derogatory word in English for those who pursue war to the detriment of their country.
The book was first written in 1971, and most of the examples are from the two world wars. The work is still extremely relevant, and at 130 pages it's well worth the time.
Highly recommended as a first book to read on ending war.

Really nice quality filter, and a good replacement for the Fram TG11665 that's now become more expensive & harder to find. 99% efficiency @ 20 micron. Pleat spacing was smooth & even with no excess glue; made in South Korea.

Perfect fit for 2019 Jeep 3.2L engine
Size: (Pack of 1)
No way to really know how a filter is doing without a close examination AFTER it is used, but then the amount of debris trapped by a filter depends on how much debris is generated by the engine. But this filter looks to be quality constriction and is rated to 15,000 miles using synthetic oil. The brand is well known and has been in business for many decades, trusted by many.
