Poland on new U.S. missile defence plan

Poland agreed to host the new U.S. Missile Defence Plan

During the Bush administration, a plan was made to set a missile defense on the Czech Republic and Poland, this missile defense was made to defend Europe from Iran.
In This year the Obama administration scrapped the missile defense made by the Bush administration.
After this, Poland opposed because they suspected the new system was being designed to appease the Russians.

The Obama administration has made a new missile defense plan which Poland has accepted to host. The plan is supposed to defend against Short- and Medium-ranged missiles.

" "Our new phased adaptive approach to missile defense is designed to meet a growing threat not only to the United States, but first and foremost to Europe," Biden said. "It's going to meet it with proven technology that will cover more of Europe including Poland and will do it more efficiently than the previous system could have or did." " (CNN)

But why does Poland accept to host the missile defense plan?
it might be because with it they will have more military power and will have the support of the U.S.
