Yes. There are no restrictions on Delaware incorporation. Anyone can do it. BUT...you would need an in-Delaware agent for service of process (basically, to receive legal documents and notifications).
Of course, international-based companies don't usually incorporate in Delaware because that would subject them to US federal income (and other) taxes, in addition to the taxes of their home country, on their full income, rather than just the income derived from their US operations. This is why multi-national corporations have separate subsidiaries in each country.
