Weak countries have no diplomacy. Every tough statement you make at the negotiating table is best supported by the capability to destroy.

In 2003, Iraq was accused of possessing weapons of mass destruction. Saddam tried to prove his innocence by showing the international investigators his underwear. But what was the result? The empty arsenal still couldn't stop the Tomahawk missiles from falling 🥲
In 2018, the same script was played out with North Korea, but the ending was reversed. North Korea revealed its big weapon, the "Hwasong-15" intercontinental missile tore through the skies over Pyongyang. The U.S. became much calmer.
When the Americans say you have something, you better really have it.
If you don't, then you're Iraq or Iran.
If you do, then you're North Korea.
