coax braid

Kirchoff's laws apply, but you're forgetting one conductor.

------A+B----coax braid-------------|

We are talking about what happens at the short on the left,
not what happens at points A or B where the coax is connected.
W8JI said the short doesn't affect the common mode current.
Seems to me, the short has approximately the same effect on
common mode currents as does a link coupling.

The coax center conductor is connected at 'A' and the braid
is connected at 'B'. Do you agree with W8JI that the common
mode current at 'X' must equal the common mode current at 'B'?
