No brother, Ababeel is kind of a vehicle, a nuclear/conventional device can be mounted on it's tip, fired and there you go to destroy a few cities. Thermonuclear is nuclear bomb, I think Pakistan does not have any thermonuclear weapons.
Bashido, Ababeel is a MIRV, which means one missile can rattle several cities. It can carry several bombs in it's tip. Enters into space, comes back into earth's atmosphere and can send havoc in several cities.
This is the first step towards ICBM, we have sent the message, no need to unnerve the West by going ahead with TIPU. We should keep ICBM in our back pocket, show it to the world if required.
Two good news in January 2017. First SLCM and now this MIRV. Excellent job and AlhamdoLilAah. Soon Indians will start a denial campaign just like they did after our SLCM test.
