Please answer a question about the following article about Franco-Prussian War:

Some historians argue that Napoleon III also sought war, particularly for the diplomatic defeat in 1866 in leveraging any benefits from the Austro-Prussian War, and he believed he would win a conflict with Prussia. They also argue that he wanted a war to resolve growing domestic political problems. Other historians, notably French historian Pierre Milza, dispute this. On 8 May 1870, shortly before the war, French voters had overwhelmingly supported Napoleon III's program in a national plebiscite, with 7,358,000 votes yes against 1,582,000 votes no, an increase of support of two million votes since the legislative elections in 1869. According to Milza, the Emperor had no need for a war to increase his popularity.

Who proposed that Emperor needed no war to increase his public appeal?
Milza
