At any rate the expedition cannot have had any great success; for shortly afterwards (A.D.

571) we find Turkish ambassadors once more visiting the Byzantine court, and entreating Justin to renounce the fifty years' peace and unite with them in a grand attack upon the common enemy, which, if assaulted simultaneously on either side, might (they argued) be almost certainly crushed.

Justin gave the ambassadors no definite reply, but renewed the alliance with Dizabul, and took seriously into consideration the question whether he should not yield to the representations made to him, and renew the war which Justinian had terminated nine years previously.
There were many circumstances which urged him towards a rupture.

The payments to be made under the fifty years' peace had in his eyes the appearance of a tribute rendered by Rome to Persia, which was, he thought, an intolerable disgrace.

A subsidy, not very dissimilar, which Justinian had allowed the Saracenic Arabs under Persian rule, he had already discontinued; and hostilities had, in consequence, already commenced between the Persian and the Roman Saracens.
