Freedom is indivisible, and when one man is enslaved, all are not free. When all are free, then we can look forward
to that day when this city will be joined as one and this
country and this great Continent of Europe in a peaceful
and hopeful globe. When that day finally comes, as it will,
the people of West Berlin can take sober satisfaction in
the fact that they were in the front lines for almost two
decades.
-John F. Kennedy,
1963

What inference does Kennedy make in this part of his
speech?

1.) The Berlin Wall will ensure that the people of
Europe remain safe.

2.) Ultimately, the Berlin Wall will not stop the spread of freedom across Europe.

3.) The Berlin Wall will come down only when West Berlin takes up arms.

4.) Fortunately, the entire world has come together to condemn the Berlin Wall.
