Pure speculation on my part:

Perhaps it's because most people believe terrorists, with no morals and not being being guided by a code of ethics,  will likely not respond to or change their actions due to protests held at universities and other public places.  I'm guessing they would not even be aware or care if there were protests held half way around the world in the US.

Countries, which are assumed to be moral and ethical, are held to a higher standard, and more easily held accountable, and to some extent care about public opinion. Thus people protest when necessary.
