You mean this question?
"Science recognizes that screening can accelerated alpha decay. How does
such screening affect the pions in their ability to keep these nucleons
inside the atom? In detail, what does screening do to the pions? What
changes?"
Based on context, I'm going to assume that what you mean by "screening"
is really "blasting nuclei with massively powered lasers". If that's not
what you mean, then you still need to explain to me what you mean by
screening.
So: the answer to your question is: it doesn't do anything to the pions.
It doesn't reduce the attractive forces. What it does is supply enough
additional energy to the nuclei that the energy hill it has to tunnel
through is shorter, increasing the probability of alpha decay.
Here's a picture.

Look at the graph for "Alpha Tunneling Model". If you raise the black
horizontal line, you'll get more red squiggles on the right hand side
(decay).
