Salisbury offered Germany in 1895 to enter the "Dreibund" of Germany, A-H and Italy, suggesting to divide up the Ottoman Empire, giving Anatolia to Germany. 1898/99 they repeated the offer and added Morocco's atlantic coast. 1901 they approached Germany again, and at this time Japan almost was a British ally, which would have made the offer even better. - Bismarck's incompetent successors always declined!
Doubt that one. In 1895 and 1896 Salisbury was kicking around various schemes to deal with the Armenian massacres
The Germans saw no reason to partition the Ottomans and were generally appalled at the ideas especially over Albania
Salisbury never offered to join the Triple Alliance and had no desire for a German Alliance
In 1902, Salisbury destroyed Chamberlain's alliance idea. A German Alliance was worthless as neither side was able to fulfill it, the Germans were terrified of the Russians and would always throw Britain overboard, Britain needed no alliance against France and a German alliance would make a colonial settlement with France impossible
Salisbury always sought to use the Triple alliance as leverage in negotiating with France and Russia
