# Inertia groups generating Galois groups [closed]

It is known that if K is a ﬁnite Galois extension of Q with Galois group G, then G is generated by the inertia groups of ramiﬁed primes in the extension.

Does the statement hold for infinite Galois extensions?

Doesn't it have to do with the fact that $\mathbf{Q}$ has no unramified extension of degree $>1$ ? – Chandan Singh Dalawat Feb 13 '11 at 11:47
