Today is the anniversary of Operation Valkyrie.
As a further explication in detail of my "What I Have Learned From the Twentieth Century," here is a thumbnail presentation of my own lessons learned from 20 July 1944:
1. Never swear a loyalty oath to a Fuhrer.
2. Acting sooner is better than acting later.
3. While it is theoretically possible to make a targeted assassination bomb too big, it is better than making one too small.
4. A shot to the head of a tyrant -- from distance or up close -- is more efficient, humane and doesn't suffer the negatives of collateral damage.
