Usd index- where to- monthly outlook

From the 2008 bottom, Usd Index has been trading mostly up and now is trading just under strong resistance that lies at 103-104 zone.
Considering the global concerns and Usd safe haven status I expect this resistance to give up and to have a dollar strength dominated year.
In the long run (one-one and a half year) a 20% increase in Usd value is not out of the question and we can see the index touching its all-time high at 120.
