This is a phenomenally bad idea.
There is no way the Giro can go to Israel without it becoming highly politicised. The following things will occur politically if the plan proceeds.
The Government of Israel will hail the decision claiming it 'proves' that the BDS movement is on its last legs, that Israel is recognised as a international sporting venue and that Israel is a beacon of stability, democracy and freedom in the middle east.
The Government of the West Bank, i.e. the PLO, will express concerns and raise at various UN fora the illegitimacy of using any part of Jerusalem that they will view as seeking to cement a legitimacy by Israel on the soverginity of the city.
Pro Palestinian organisations, particularly in Europe will mobilise massive recourses, manpower and time into trying to organise a boycott - putting pressure on the teams, individual riders and their sponsors. A potential boycott that the likes of Bora, Sunweb, AG2R etc could really do without.
Pro Israeli organistions, their embassies and Israeli 'internet activists' will counter with their own campaigns aimed at the same teams, individual riders and their sponsors.
A boycott of the event by Bahrain Merida and UAE world tour teams causing a crisis in UCI.
A boycott by other riders or even teams citing 'security concerns'
A boycott by some riders on the basis of their own political beliefs.
If then it still goes ahead in what will be by now a highly charged event the following will definitely happen.
A security lockdown of unprecedented proportions of all of the West Bank, East Jersulaem and the Gaza Strip by heavily armed Israeli security which will disrupt, antagonise and negate any possible goodwill that the event could bring.
And the following could happen.
One of the more extreme armed groups (not Hamas or anyone from PA) could decide to disrupt the race by either an attack or just the threat of an attack.
And the final reason is that Israel Cycling Academy would get a wild card entry and they definitely are no good enough.
So all in all a bad, bad, bad idea the only possible beneficiaries of which are RCS who stand to get some cash for their coffers from the Israeli State. For all else its just a load of grief and worry.
In this case it is literally not possible to separate the sporting from the politics as, following an official announcement that the Giro will start in Israel in 2018, if the race proceeds that will be used to make a political point and if the race doesn't proceed as planned that will equally used to make a political point.
