Maybe you don't realize that some of the biggest protests before the US invaded Iraq took place in Spain. Millions of people protested in that country so it is clear it was not the will of the people that Spain go to Iraq. And as a sovereign nation they are well within their rights to do what they want in regards to this. The spanish Gov't was fulfilling a campaign promise too. Something maybe Americans aren't understanding too well these days.

But don't worry, you still have such military powerhouses as El Salvador and Nicaragua in Iraq. ;)
