Could von Spee have brought his squadron home before the war?

What if von Spee's squadron had been recalled to Germany before the First World War?

A prompt recall might have brought it home through Suez before hostilities, but the decision window was extremely short.

The answer thinks the squadron could have returned if Berlin acted as soon as war appeared imminent. Before formal hostilities, Britain would have little reason to block a German passage through the Suez Canal because sending the ships home removed them from overseas commerce warfare. The narrow window depended on a rapid political decision that Wilhelm II was unlikely to make. A later follow-up stresses that von Spee and the squadron's trained crews would have been more useful in European waters than on the doomed historical cruise.
