Strength of any bond depends upon the length of the bond.

Let's take an example of a stick which stick is easier to break a longer one or a shorter one, obviously the longer one.

Similarly, Longer the bond more easy to break, shorter the bond more difficult to break.
Since s-s bond are the shortest hence strongest than s-p or p-p bonds.

Please note s-s bond are close to nucleus to a limited extent as after that inter-nuclei
repulsive force are being generated. They can't go closer beyond that extent but that doesn't mean it is making the bond unstable.
