Pakistan, terrorist country?

At last Zardari has accepted that certain terrorist organizations are operating in Pakistan. Zardari told in a press report that there are some terrorist organization which is operating and getting trained in the Pakistan territory. India was very strong and very sure that this was happening in the Pakistan territory. But the thing is why Pakistan has come up with this comment after being in a denial mode that Pakistan is a safe country? I really don’t understand what is happening in Pakistan, initially they told no terrorist organization is there in Pakistan and now they are accepting that terrorist organization is there in Pakistan and the entire world is watching this. It is really disgusting to be a neighbor of a terrorist country.
