what to trade when usd is bought as safe haven

When political unrest - eg Eqypt - I do understand that as USD is a safe haven currency (and therefore goes up) - wot i am finding difficult now is (as opposed to when i first started trading) what currencies would you buy to get a profit from USD going up. FOR EXAMPLE If AUD is strong based on commodities and our mining shares are doing well AUD would not necessarily be the trade to select - I am at a loss as the more I read etc the harder it is to make a decision - aahh in the beginning my ignorance shielded me (but not my trading account) any comments would be much appreciated. bmer
