"The IDF said poor weather conditions were probably the cause"

The advocates of expensive missile early warning systems, and, particularly, anti-missile missile systems always quote their manufacturers` test results.
These tests are conducted under perfect conditions, and often with the time, direction and location of the incoming missiles known.
With ballistic missile defence systems there`s often a homing beacon in the incoming warhead to flatter results.
Apart from adverse weather conditions, human error has to be factored in - the Israeli warship hit by a Hezbollah drone had a defensive system but they had neglected to switch it on.
Should war ever break out between America and Iran, US capital ships are at major risk in the Gulf, particularly from the top-of-the-range cruise missiles the Iranians have bought.
