Maybe not under normal circumstances but we're not living through normal circumstances here.
In terms of it's size Iceland suffered the biggest banking collapse in world financial history. That kind of thing can have quite significant consequences.
A valid point.... the following lends to that line of thought....

"Where does the crisis go next? Most exposed are countries with large amounts of external debt relative to the size of their economy. A quick calculation suggests that by this measure, the U.S. is relatively well off, with external debt about equal to GDP. Japan’s external debt is about 40-50% of GDP, as is Canada’s (these numbers may change as I refine my calculations). Italy is at about 100%, and Germany and France are in the 140-150% range.
From this perspective, the U.S.—with its external debt mostly in dollars—looks like a bastion of stability. The euro zone has some weaknesses—Belgium and the Netherlands have uncomfortably high debt levels, and Ireland is extremely high. But there is a political framework in place which should allow political leaders to take effective action if they want.
The biggest dangers are for the UK and Switzerland. These countries, although much bigger than Iceland, are major financial intermediaries with big external debts. What’s more, they are outside the major currency blocs, with debt denominated in foreign currencies. That means if their currency starts to devalue, their debts will become more and more onerous.
And now we are in very tricky waters, which are looking uncomfortably like the Great Depression. The major players are the U.S., the Eurozone, Japan, and China. The question is: Will they act collectively, or will they engage beggar-thy neighbor policies? "
