Both small states haunted by the fear (real or imagined) that they are encircled by volatile and hostile neighbours, Singapore and Israel have long cooperated on military matters, trading arms and helping to train each other's forces.
In an intriguing story, Israel's most influential newspaper, Haaretz, claims that their latest joint project is a missile defence system that is being developed by an Israeli company with Singaporean financing.
The story claims that Singapore has helped to fund the $250m Iron Dome, which is designed to intercept short-range missiles and rockets, in exchange for several of the systems, which it intends to deploy in the Lion City.
Haaretz has picked the story up from Intelligence Online, a paid-for industry news publication. (You can read the original here for the bargain price of 7 euros - I haven't.)
The Intelligence Online story begins: "Some Israeli arms programs are too costly for the local market and are developed principally for export. The anti-missile system Kipat Barzel (Iron Dome), is a typical example. The system is currently being tested in the field by the Israeli Army before being delivered to Singapore."
If true, it is hardly surprising that Singapore and Israel are continuing to further their close military relationship.
But I can't imagine what Singapore would want with a short-range missile defence system.
Despite the similarities between Singapore and Israel, the security threat is mostly imagined in the case of the former.
If Malaysia or Indonesia ever want to get at Singapore - and it's highly unlikely given how many members of the Indonesian and Malaysian elite secrete their personal wealth there - they need only cut off the water or gas supply.
But, on the off chance that rogue Islamists or unhinged nationalists ever fire Qassam rockets at Singapore from Pulau Bintan or Johor, Singapore will soon be protected (if this story is true).
