A diode will appear as a short when it is forward biased, but will produce a predictable voltage drop, usually on the order of 1 volt. No matter what resistor you put in series, the voltage on the diode will not change (within reason). Only the current changes. The power dissipated by the diode is the voltage drop multiplied by the current. Without a resistor the current will not be limited and the diode will blow. 12 diodes in series will drop (roughly) 12 volts but the current will still be unlimited.
