Clearly, it involves Israel and a few Arab Sunni states who all have a mutual rival - or enemy - in Iran.
Mr Lee made clear Singapore's stand on a two-state solution when he met Mr Netanyahu in Israel previous year.
Turnbull says his government's position in support of a two-state solution has not changed. "I'm very happy with the one that both parties like". The US was invited to get involved only when the talks produced a promising - so the leaders of Israel thought at the time - beginning.
There is nothing to object to about a single state in which Israelis and Palestinians enjoy equal and democratic rights, secure land ownership, and a high degree of autonomy under some confederal pact.
That reason: the demographic threat.
"We have consistently believed that a two-state solution between Israel and Palestine, however hard to achieve, is the only way to bring peace and security to both peoples and to the Middle East", he said. There was at that time 10 percent of the population, 175,000 Arabs, remaining in Israel who are there yet today. Since Trump took office last month, Israel has announced plans to build over 6,000 settler homes in the West Bank and east Jerusalem, illegally occupied territories claimed by the Palestinians. The Fine Gael programme for government pledged to "honour our commitment to recognise the state of Palestine". But presidential words on such key topics are bound to have consequences. Even though the concept was already on life support, there was good reason to keep it alive.
Hyams told the ABC that the letter ignored that Israel took the West Bank in a defensive war in 1967 and then offered to return most of the land, and has made "three generous peace offers since then".
The global community sees settlements as a major obstacle to peace, as they are built on land the Palestinians see as part of their future state.
NFL Morning After: The Decline of Colin Kaepernick

The former US administration criticized Israel's continuous expansion of the settlements, which it considered as a major obstacle to peace.
Australian Foreign Minister Julie Bishop met with Netanyahu in Jerusalem in September and invited him to become the first Israeli premier to visit the pacific continent.
"This is one of the things that contribute to strengthening Israel's economy".
If the two-state solution is dead, what is the alternative? "The regional partners are there, but they will not be able to be seen publicly moving toward a regional process without some compensation on the Palestinian front", he said.
Former Labor prime minister Bob Hawke has called for diplomatic recognition of Palestine, sparking what is a healthy debate about how Australia can best support the quest for peace. That opens a Pandora's box of questions about what rights Palestinians would have within one state.
Yet few Israelis are likely to agree with Rivlin's formulation. It has shown itself willing to stand against the vast majority of the worldwide community on the issue, rejecting for example the refrain that east Jerusalem is "occupied Palestinian territory".
"It might be a nonfederal or autonomous system, where Palestinians are present", but never a two-state solution, the analyst added. This is not a matter for careless phraseology or tweets.
