For example, you could be selling a million widgets in America and be certain that they would be a big hit in Europe. However, if you are planning a major redesign, or foresee having problems obtaining raw materials in the future, you may need to rethink your strategy. Or, if technological advances in your industry might make a product obsolete in five or even 10 years, foreign expansion might not be prudent. (Alternately, there are likely underdeveloped countries that might welcome a product that the major industrialized nations no longer need or use.)
