Can a Nuclear Blast Alter Earth's Rotation?

The nuclear bombs are human’s most powerful explosive device. Can this device alter the spin of the axis of the earth?
There’s one way to find out is to compare the energy of the nuclear explosion to rotational motion of the earth. The largest nuclear bombs can blast of an energy of several tens of a megatons, or about 10^17 Joules. Where the earth rotational energy are approximately around 10^29 Joules.
So even if the explosions of the nuclear bomb are use in a specific direction, the energy in this push would be less than a trillionth that of the rotational energy.
It would be like trying to divert a speeding truck with the energy of a flying insect.
