Why a massive body is easier to break than a tiny body?

Why a massive body is easier to break than a tiny body despite the force bonding two particle is the same?

It's not.

Why a massive atomic nucleus is easy to break down?Is one nucleon acted by "multipoles" force but not interaction direct between two nucleons and "multipoles" force is weak with large nucleus?But strong interaction always is attractive force not have both repulsion and attractive force as electric force,then how can we make up a multipoles?

Now I rethink that with a large nucleus the "Van der Waals" "color" is nearly "white"(QCD) so the van der Waals force binding nucleons with each other is weak.Is that correct?

I have no idea what you are talking about.

If you are talking specifically about nuclei and not generic "massive bodies", you should say so.

At the beginning I thought that in general the big thing is easier to break,but by your answer I know that I was wrong.But after that I did not understand about the big nucleus!
