European sympathy was almost wholly with Spain.

The French, for instance, had invested heavily in Spanish bonds, many of which were secured on the Cuban revenues.

There was also perhaps some sense of solidarity among the Latin races in Europe and a feeling that the United States was a colossus willfully exerting itself against a weak antagonist.

It was not likely that this feeling was strong enough to lead to action, but at least during that summer of 1898 it was somewhat unpleasant for American tourists in Paris, and an untoward episode might easily have brought unfriendly sentiment to a dangerous head.

Austria had never been very friendly to the United States, particularly since the execution of the Emperor Maximilian in Mexico, which his brother Francis Joseph believed the United States could have prevented, and was tied to Spain by the fact that the Queen Regent was an Austrian Hapsburg.
It was evident, moreover, that in Europe there was a vague but nevertheless real dread of the economic potentialities of the United States--a fear which led, in the next few years, to the suggestion that the American invasion of trade should be resisted by a general European economic organization which would even overrule the natural tendency of powers to group themselves into hostile camps.
