According to the Constitution, the Hungarian Parliament is sovereign in the Hungarian State, and without the use of armed means Hungary could never have been induced to cede any part of her territory.
It is obvious, however, that it would have been impossible during the world war to have stirred up an armed conflict between Vienna and Budapest.

My then German colleague, von dem Busche, entirely agreed with me that Hungary ought to make some territorial sacrifices in order to encourage Roumania's intervention.

I firmly believe that then, and similarly before the Italian declaration of war, a certain pressure was brought to bear direct on Vienna by Berlin to this end--a pressure which merely contributed to strengthen and intensify Tisza's opposition.

For Germany, the question was far simpler; she had drawn payment for her great gains from a foreign source.

The cession of the Bukovina might possibly have been effected, as Stuergkh did not object, but that alone would not have satisfied Roumania.
It was quite clear that the opposition to the ceding of Transylvania originated in Hungary.
